[Webware-discuss] Anyone seen WebKit processes going into a weird state?

[Hancock, D. (DHANCOCK) <DHA...@ar...>]

Several times a week on our production systems, we're seeing our WebKit
processes (normally entitled "python Launch.py ThreadedAppServer") lose
their command lines in the output from ps.  They're also well wedged, and
the processes need to be killed by hand to clear this situation.  Has
anybody else seen this and have some ideas to help us troubleshoot?  For
now, we're detecting the situation with automated monitoring (and
process-killing and webkit-restarting), but we'd sure like to know how we
can prevent it, not just work around it.

Output from ps auxww:

adc      25799  0.1  1.6 130288 34252 ?      SN   Jul28  10:04 [python]

adc      25810  0.0  1.6 130288 34252 ?      SN   Jul28   3:37 [python]

Our setup includes:

	Python 2.2
	Webware 0.8
	RedHat Linux 7.3
	A  couple C extensions: DCOracle2 and pymqi (interface to IBM's
MQSeries)

Thanks in advance for any ideas and assistance.

P.S. We had an extreme example of something similar several months ago, but
even the "[python]" was missing from the ps output. Thus, it didn't look
like WebKit was running at all, but a start attempt couldn't bind to the
port. We could only find the culprit process with "netstat -anp | grep 8086"
run as root.  I don't know if that failure is related, though, it was just
weird.

Cheers!
