[Bug 368201] Re: gnome (or firefox) 99%hangs system
I've seen a very similar (most likely the same root cause) problem. I think the key is the high load, low CPU, and extreme unresponsiveness. My guess is that the system is waiting for disk resources, and queueing up on the CPU. Any suggestions on what information to gather to test that hypothesis would be appreciated. I'm running 64 bit Ubuntu 8.10, 2.6.27-17-generic, reiserfs with software raid 1. My box exports file system mounts through both NFS and Samba. The next time it happens, I'll try (if I can get it to respond) to gather more info. -- gnome (or firefox) 99%hangs system https://bugs.launchpad.net/bugs/368201 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Well, it's not Gnome or Firefox specific. It's now hung when Firefox wasn't loaded and again, twice, when running with KDE.

The problem has returned and seems to occur once or twice a day. However, was able to SSH into machine and run apport-collect -l linux 368201 Although '-l linux' wasn't a recognised option so just ran it as apport-collect 368201 Which gave the somewhat limited information, above.
