I have a motif based application that runs on Fedora 9. This application has a functionality that calls itself periodically to perform a task using SIGALRM signal.

However the application seems to crash after a while.

Examining the logs, the X server seems to be crashing with the following logs:

*XIO: fatal IO error 2 (No such file or directory) on X server ":0.0" after 24275 requests (23960 known processed) with 0 events remaining.*

Could someone please tell me what could be the problem?

Fedora 9 is very old, can you try running the same application on a newer version of Fedora? – Renan Jul 17 '12 at 14:29

I have never had that problem, but searching the Internet yields a similar problem which is finally traced down to a driver problem. Why are you still running Fedora 9? With a system that old you may not even be able to compile recent drivers for your video card ...

Thanks, but this seems to have nothing to do with the video card. The problem seems to be related to the way events may be processed by the X server. – arun nath Jul 17 '12 at 11:01
You are correct I wouldn't rule out that the Xserver code has changed during the last 8 (!) release cycles ... maybe you want to upgrade? – Bananguin Jul 17 '12 at 22:07
