XIO: fatal IO error 0 (Success) on X server

16 Jul 2003

      I have a SuSE8.1 system installed with the XFree86 4.3.0 packages from
SuSE for 8.1 and KDE 3.1 on top of that (all rpms are from SuSE for 
8.1).  50% of the times that I run an
application we wrote I get the following error:
XIO:  fatal IO error 0 (Success) on X server "ebony:0.0"
      after 14 requests (13 known processed) with 0 events remaining.

then that is it and it exits.  The other 50% of the time it runs
perfectly.  NOTE: I compiled the application using gcc3.1.  If I compile
it on a SuSE7.1 system with the SuSE X 4.2.0 packages and then run it on
a SuSE8.1 system it works fine.  Also note: this happens on all of the
SuSe8.1 system I have (about 20 or so) so it can't be specific to Video
card (they all have various cards).  Bellow is the last lines of an
strace on the application.  Note: DRI is setup and working and loads
just fine from the looks of the X log.

Any clues??
thanks
