Subject: 3.0-rc3 stuck process in munmap()
Date: 17 Jun 2011 05:24:54 -0400 [thread overview]
Message-ID: <20110617092454.497.qmail@science.horizon.com> (raw)
As a followup to my report of firefox getting stuck in 3.0-rc1, here's the
problem repeated on -rc3. top(1) can produce the process status, but
"ps axf" hangs before printing anything.
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
2821 username 20 0 1453m 964m 18m D 0 47.8 1434:51 firefox-bin
Core 2 duo, 2 GB RAM, NO_HZ=y, MZ=300, PREEMPT_VOLUNTARY=y.
It's been stuck for about half an hour so far.
I wasn't using Firefox when I noticed that it wasn't refreshing its
window when I changed to that screen.
I'm not going to reboot in case someone wants information gathered
this time.
