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:

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!
