By lockup, I mean that it stops responding to the keyboard and uses 100% CPU. It will sometimes go for days with no problems, but I had two yesterday, and other today. They have occurred on test systems running in VirtualBox and on a real computer, both i386 and amd64 images, and a mixture of 7.1, 7.3 and 8.0. They usually seem to happen when I am switching tabs in konsole or switching shells in screen, but other times I think they happen when I am not even using the system. The only thing I have found I can do is to do a kill -9 and start a new shell. Does anybody have any suggestings on how I could try to trace this? I haven't been able to find any bug reports, but I don't know enough to know how to search the FreeBSD problem reports very well. Thanks for any help. I already subscribe to this list, so there is no need to cc me. -- Carl Johnson carlj@peak.org
