I am using XFree86 4.2.1 on Redhat 7.3 with kernel version 2.4.22. The X server seems to be infinite looping -- top says it is utilizing 99.9% of the CPU. I suspect an X client application is involved though I don't know if it is the cause or a victim. Here's a backtrace of the X client (I'm including the loading of symbols just in case something in it is useful): GNU gdb Red Hat Linux (5.1.90CVS-5) Copyright 2002 Free Software Foundation, Inc.

Does anything in the above backtrace indicate whether the X client was the cause or the victim of this problem? If additional information would be useful toward diagnosing this problem then please let me know and I will get it! --Joel |
