Subject: [gentoo-dev] System hangup w/ X taking 100% cpu
Date: Thu, 13 Dec 2001 11:11:25
1 Hi all,
3 On my new r12 system I've had a hangup in X11. No apparent cause. The system
4 stopped accepting any input and the screen didn't even complete a redraw. The
5 mouse went on moving as it was in h/w, but clicks were no good. Magic sysrq
6 wasn't responding either.
8 I logged in via ssh, and top showed X was taking 100% cpu. I tried killall X,
9 no effect. I tried kill -9 <X pid>, the remote login hung up and i couldn't
10 ssh to it again. I had to do a hard reboot.
12 Then I expirienced the same effect twice on an old rc5 system which underwent
13 absolutely no updates or config changes for a few months now. Only this was
14 standalone not on a net, so I couldn't login via ssh.
16 Both rc6 lockups were when running kmail, both rc5 lockups while running
17 ksirc.
19 Trying to send this message, I had another lockup on the rc6 system, hope
20 this reaches you.
22 I'm absolutely mystified. Ideas? Anyone seen this kind of thing before?
