FSUIPC6 preventing P3Dv5 closing fully


Recommended Posts

I have been experiencing problems running FSUIPC6 6.0.1 with P3Dv5. On exiting P3Dv5 a background task of size 323KB remains running. It is labeled variously as Prepar3d, Prepar3d Scenario Startup and Lockhead Martin Prepar3D v5. This is causing issues running P3Dv5/FSUIPC6 subsequently. The background task has to stopped manually in Task Manager to restore correct operation.

I used the P3Dv5 options to disable FSUIPC6. The problem does not occur and all P3D tasks stop on exiting. I conclude that the hanging background task relates to FSUIPC6 not closing properly.

Further information. The same issue affects P3Dv.5 running with FSUIPC6 6.0.1. The fsuipc6.logs (attached) show that all processes are being closed but P3D background task remains running. Only by ending the hanging task am I able to get LINDA (my supported app) to run correctly (ie. interacting with FSUIPC6) on next P3D start.

EDIT: One further indication that FSUIPC6 is still running is that I was unable to rename the fsuipc6.log files until I closed the hanging background task.

FSUIPC6 back on produced the hanging background task on exiting P3D.

So this occurs with FSUIPC6 being the only add-on?

Could you download and try v6.0.2 please. No specific fix for this (as I cannot reproduce) but I would like to know if the problem still exists in this version for you.

Hi John

Sorry to bring you more problems.

I stripped out all other add-ons including all LINDA code and still got the hanging background task. FSUIPC.log is also locked from being renamed until End Task is used.

I installed FSUIPC6 6.0.2 into the user/add-ons/fsuipc6 folder and I am still seeing the problem (see screenshot below). I also this time got the duplicate FSUIPC copies running error dialog on one occasion. On exiting P3Dv5 FSUIPC6 is correctly closing the running programs (via [programs]) but the process is still hanging and has to be stopped manually.

Hi,

you said all of Linda is stripped out but the that doesn't close you sent shows this? Can you please send the log from a session without Linda .

Hi Thomas

The logs provided were with LINDA added back but the hanging task was there is all cases. The attached log is with FSUIPC6 as the only Add-on in P3Dv5. It causes the same issue.

What I did observed in Task Manager as P3D/FSUIPC6 shuts down:

  • Background Task Prepar3D.exe sized at ~= 750KB.
  • The VRI panel flashes as it resets. Size is 500KB.
  • Background Task Prepar3D.exe shown briefly as 'suspended'
  • Background Task Prepar3D.exe reduces to size 300KB and remains running.

Just to add to this, in case it helps. When this sort of thing occurs, with possibly only one of FSUIPC's many threads not terminating, it is nearly always down to some driver or other which has been used by a plug-in and has hung, simply not returning. 

Since FSUIPC thinks it has successfuly closed everything such eventualities are not only difficult to diagnose, but impossible (as far as i can see) to program against. Lua threads which are created by FSUIPC are forcibly terminated if they don't go quietly (in the same manneras terminating a hung process via Task Manager) but there's nothing to stop Lua-started DLLs creating subthreads which FSUIPC isn't aware of.

I can only think that a process of elimination amongst the many parts of LINDA (which I've never been able to fathom) might get to the cause.

Ah. That log is clearer and actually shows that FSUIPC is not terminating at all.  The Log shows it is hanging "Closing devices". 

So, try without the Arduino and the VRI devices.  Some software driver associated which one or the other is not terminating. (The other devices look pretty innocuous).

Hi Pete

Thank you for your valuable insight. I ran a series of tests*** with all devices removed (except CH Flightstick), with VRI Combo added, and with all devices except the VRI Combo. You are correct.

It would appear to be the VRI Combo connected to COM3 that is the cause of the hanging background task. There are no software or drivers running with the VRI except the FDTI USB to Serial device drivers necessary to communicate to FSUIPC. This has not been an issue that I have seen previously.

NOTE: *** the tests involved disconnecting/connecting devices in turn, starting P3Dv5, operating the Pan View on the CH Flightstick, closing P3Dv5 and observing the Task Manager.

You'd think a problem like that would affect P3D4 as well. Does it?

I used to have lots of problems with cheaper end USB-Serial adapters. My PFC equipment (and my GS28R VFR cockpit) depends on good RS232 comms. I found Brainboxes to be the best make for sheer reliability and not hanging during transfers. Some others seem to hang as soon as you let their FIFO buffer fill.

Brainboxes do PCI and PCI-E cards, avoiding USB altogether, and also, more recently, two different USB adapters -- one high capacilty one with a really big FIFO buffer. Expensive though, compared to the dirt cheap ones.

Hi Pete

P3Dv5 runs correctly regardless of whether the hanging task is there or not. LINDA button inputs to FSUIPC6 and FSUIPC6 axis inputs both work as normal. The main issue and how I spotted the problem is the display of FSUIPC6 log output (including LINDA lines) on the LINDA debug tracer. The logging is actually going to the fsuipc6.log as you can see. Also there is no communication with the VRI Combo Panel is the fault condition.

There is something blocking both the VRI output and FSUIPC/LINDA communication via IPC.

I don't think looking at changing the VRI USB output is practical for me or our users.

So, what would you suggest? And is this new? What about on P3D4 (I did ask!)?

It was not a problem that affected P3Dv4.5 with FSUIPC5. The only change was one you put in to stop the CMDRST command being sent to the VRI Combo (fsuipc5.ini parameter VRIDisableCMDRST) for some users with particular hardware issues.

Is it possible to force the VRI processes to close on shutdown?

The problem is affecting FSUIPC6 with both P3D v5 and v4.5. It was not apparent in FSUIPC5 with P3D v4.5.

That's most odd. I'm sure there's been no change in the area of COMs support.  I can only think it's a matter of a small timing change ... or, just possibly, a change in the Microsoft Libraries  we are using. (We updated to a later version of Visual Studio for the new version, matching the change in P3D).

We might look to see if it is confined to a COM thread which can be ruthlessly terminated after a tineout of some description. But it might be better to first see if there's some logging we can turn on or add to narrow it down to the particular system call which is not returning.

It's late here now, and Sunday isn't a good day for me work-wise, so I'll discuss it with John on Monday and see what we can do. Meanwhile please remain with the use of Task Manager.

Hi John

I ran both 6.0.3 and 603b. In both cases I was left with the hanging Prepar3D Scenario Startup task (size 640MB). This task had to be manually stopped to enable P3Dv5 to start with VRI Comb panel working. The FSUIPC5.log was locked by this task preventing the log being renamed. LINDA was used to allow the MCP to be tested.

Exiting P3Dv5 with 6.0.3b is causing P3Dv5 to crash on exit. There is no hanging task in this case.

I also ran P3Dv4.5 with 6.0.3 as a comparison. This left a hanging task Lockhead Martin Prepar3D (size 182MB). Also the MCP did not reset on FSUIPC6 shutdown (CMDRST instruction not sent).

I will later setup FSUIPC5 with P3Dv4.5 again to see if I can reproduce the problem.

I attach a series of logs renamed to indicate the different tests.

Also the MCP did not reset on FSUIPC6 shutdown (CMDRST instruction not sent).

Do you have the VRIDisableCMDRST parameter set to Yes in the ini by any chance?

I am very surprised that the first dll didn't work (which is actually 6.0.3a but I forgot to update the character string, sorry) as this should be equivalent to FSUIPC5...

I'll discuss with Pete to add some logging to try and track down this issue...

Hi John

As my VRI Combo panel did not have the previous COM connection issue (reported by some MCP owners), I had not included VRIDisableCMDRST in fsuipc6.ini.

However, your question was very apt. Using 6.0.3a with VRIDisableCMDRST=Yes, P3Dv5 correctly closed with no hanging tasks. No CMDRST instruction was sent on startup or close down. Setting VRIDisableCMDRST=No caused the task to hang!

Just to test this result, I changed the option back to Yes. On 3 occasions P3Dv5 crashed on exit. On the 4th attempt, the task hanged up again. On the 5th attempt, it worked correctly. On 2 further tests, P3Dv5 crashed and then hanged on the background task. I am not sure this helps.

NOTE: With 6.0.3 the offset with the FSUIPC6 version number (that LINDA reads) is now correctly populated.

Hi Andrew,

strange and confusing results...any ideas as to what is causing P3Dv5 to crash?

Could you try the following dll please (6.0.3d): FSUIPC6.dll

It has additional logging. Start with only the following in your ini:
    Debug=Please
    LogExtras=1

Just before you close the session, go into the logging tab and set the extras value to 8197.

If you could then generate a log when iy hangs. Thanks,

John

Hi John

Test ran with 6.0.3d. Closed correctly. In a number of follow on tests, P3Dv5 crashed on shutdown. This occurred before [programs] started LINDA was terminated.

I did a further test with LINDA running independently of FSUIPC6 and the result was successful (2nd). I see that FSUIPC6 did not fully close the log. One final test (3rd) in the same conditions terminated fully and the log is complete.
