I'd say you're being overly kind, if your users are remotely
like mine. One thing I like about the BSD variants is the daily
report of segfaults (amongst many other things). From this, I
know that the users of AbiWord, OpenOffice, various KDE bits,
Mozilla, Netscape and Opera experience regular crashes and they
never report any of these -- in fact, if I ring up and ask how
things are going the morning after a flurry of this sort of
thing, they'll always tell me that everything is great[1].

It's something to consider if other steps don't produce results,
but it certainly sounds as if you have other things that would
be worth exploring first.

I'd second the suggestion to rebuild the whole apache suite with
care from the latest sources and see how it goes.
Cheers, Greg
[1] If I ring up and say something like: "you had a problem
yesterday with a dud floppy when you were transferring data
from the Windows box to [a FreeBSD box]", they say: "Wow!
How did you know that?" and my god-like reputation is
raised a little bit further -- but only because I take the
few minutes to read each daily report.
I don't bother to point out all the core dumps in the
bloatware, because there's nothing I can do about them and
there's no point in making an issue about it if the users
don't care enough to complain.
