IPC sendmessage failed all retries

[Patrick_Manzi]

Hello,

I'm using FSUIPC to communicate between my own application and WideFS which then talks to MSFS2004 on another computer.

For the most part, this works well, but sometimes I get the following error:

IPC sendmessage failed all retries

This error remains until I reboot both my own computer and the computer running MSFS.

Is there anyone out there who knows:

1. What this error means.

2. What are the commong causes of it.

Thanks in advance for your help,

/Pat

PS - and yes I have purchased both WideFS and FSUIPC!

Have you tested your program direct to FSUIPC at all?

What does the WideClient Log show? What versions of WideFS and FSUIPC are you using?

Is there anyone out there who knows:

1. What this error means.

It means that after a number of retries your program could not get an answer from WideClient or FSUIPC, whichever it is running on. It uses "SendMessageTimeout" and wants a response within a timeout period. when FS is really busy that timeout may occur, so the library code I provide does a number of retries. Provided FS is available within about 10-20 seconds it should work. Otherwise you get that error.

However, in the case of WideClient, even if FS is busy or even if it isdn't actually running, the response to the SendMessageTimeout from WideClient.exe is nearly always immediate. If you are getting such failures on a client then it sounds like WideClient isn't running, or is hung, or has crashed.
