[Bug 910287] Re: ps hangs when listing root processes
I just upgraded from 16.04 (via >16.10) to 17.04 and now I'm seeing this too. I tried the strace and observed that ps was hanging trying to list the commandline of the thunderbird process. I had already exited Thunderbird and there were no indications in the GUI that it was still running. I had no luck getting rid of the process with kill -9. Also I could not shut the machine down cleanly. I did findi a bunch of NMI watchdog: BUG: soft lockup messages in syslog, which I'll attach to the bug report. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/910287 Title: ps hangs when listing root processes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/procps/+bug/910287/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 910287] Re: ps hangs when listing root processes
Currently have this problem on 12.04 when running as root and running
'ps -ef'. 'ps' alone works. 'top' works. Below, the output of strace
where it hangs. Seams that the problem is Xorg in my case. I just
switch my computer to the proprietary ATI driver. Still, regardless of
what is running, ps (or the underlining /proc) should never hang. I
tried the following and it hangs too. CTRL-C does not help.
# cat /proc/1899/cmdline
strace of ps:
[... deleted lines ...]
write(1, bind 1881 1 0 07:35 ? ..., 72bind 1881 1 0 07:35
?00:00:00 /usr/sbin/named -u bind

I'm getting this also. I have a Skype instance that doesn't terminate when closed, but otherwise appears to function normally. When I list all processes with ps -ax, it hangs and can't be killed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/910287 Title: ps hangs when listing root processes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/procps/+bug/910287/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
