Description Andy Burns 2005-12-01 14:23:23 UTC
Description of problem:

System sometimes gets into a state where "ps -ef" hangs completely

Version-Release number of selected component (if applicable):

# rpm -q -f /bin/ps

# ps -V
procps version 3.2.6

How reproducible:

This has happened twice to me now, 
I don't know how to force it to happen again, but once it starts it remains
until a reboot.

Steps to Reproduce:
1. ???
Actual results:

"ps -ef" prints a partial process listing, then hangs mid-output, can't be
stopped with ^C ^D ^Z etc

Expected results:

finishes process listing

Additional info:

While "ps -ef" was hanging, I tried to use top to see if it would also hang, but
it worked OK, I couldn't spot any rogue processes that might be upsetting ps,
however gnome-system-monitor refused to startup so maybe it is caught by the
same problem.

a "ps" with no argcuments does run properly.

I realise this alone is not enough to diagnose the issue, given that it has
happened twice in a few days, I assume it will happen to me again, if/when it
does any suggestions on further information that can be obtained at that time? a
listing of /proc perhaps?

Haven't seen this re-occur in any recent kernels, probably best to resolve as
worksforme ...
