I've actually run into something similar, I was planning to post
something about it. I've set up Webware (0.8.1) on a Redhat 9.0 machine
and I'm using Apache 2.0.48 and mod_webkit2. During my testing I've
started to notice some stability issues. Webware just seems to lock up,
it doesn't return any errors, it just doesn't respond, or if it does
respond it's like a couple of minutes later.
After seeing your post I'm beggining to wonder whether it might be a RH
9 issue. I did all of the development work and early testing on my
Mandrake 9.2 desktop and am now moving things over to the production
machine. These stability issues are starting to get me a little
One thing that it may be though, is that I'm running Apache on one
machine and Webware and PostgreSQL on another. Anyone know of any
issues with this type of a setup?
As a side note, the reason you may not be seeing the zombie process
and/or threads is that apparently under RH 9 ps won't show threads by
default. This confused me earlier until someone on this list told me to
add the -m option (eg. ps -efm). That might make it easier to find the
Anyway, I don't have anything that will help you, but I'm hoping an
account of a similar problem might shed some light on the situation.
