Sorry for the long delay in responding, we have ended up going with
prefork and everything seems to be stable with it - a slightly

We have a lot of users running Apache worker and
prefork. However to be honest i don't remember anyone that contact
me using event. So, as i never saw a report about this issue using
worker and prefork... you can try both and send us a feedback.

But the threaded nature of the Apache processes when using the
worker MPMs means that all modules must be programmed
Most of the popular ones are though.
If that is an option for you, chances are good the problem
