Hello!
It's been a while since I last saw an unkillable process on -current,
but here it is -- on 5.2-RELEASE. From ps(1):
UID PID PPID CPU PRI NI VSZ RSS MWCHAN STAT TT TIME COMMAND
1042 14627 1 0 96 0 61216 49300 - W pa
4:34,22 ./mozilla-bin http://www.ex[...]
and from top(1):
PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU
COMMAND
14627 mteterin 96 0 61216K 49300K WAIT 4:34 0.00% 0.00%
mozilla-bin
The ps(1) seems to indicate, ``The process is swapped out'', so here is my
swap:
Device 1K-blocks Used Avail Capacity
/dev/ad2b 524288 36 524252 0%
/dev/md8 1572864 44 1572820 0%
Total 2097152 80 2097072 0%
(md8 is vnode-backed using the pagefile.sys on Windows partition, ad2 is
a separate disk, used by FreeBSD entirely).
The process has been in this state since Thursday, Jan 29th -- it seemed
to have hung and I tried to kill it. Numerous ``kill'', ``kill -9'' were
ineffective. Although xkill(1) helped me get rid of the window, the process
still lives and accounted for another bit of CPU time:
1042 14627 1 0 76 0 61216 49276 - W pa
4:34,23 ./mozilla-bin http://www.extr[...]
None of the directories used by this process according to fstat is
nfs-backed. A freshly built lsof does not list ANY files as opened by
the PID.
An attempt to attach a debugger (gdb) to the process hangs.
Any clues? Thanks!
