Description David Juran 2005-04-10 10:09:09 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050323 Firefox/1.0.2 Fedora/1.0.2-1.3.1

Description of problem:
If hyperball, from xscreensaver-4.18-4 is left alone running for a few hours X locks up. The screen and keyboard is locked, but I still could log in on a serial console. I then noticed that X was hogging the CPU.

Below is a stacktrace of the hyperball process.
