This is very big question. You should research perl best practices
for development. You should also research secure programming
techniques.

If you don't have an unbounded growth issue it is likely do to some
library pulling in alot of dependencies or the creation/caching in
memory of some large data structure. You can preload all the
offending libraries and see if that causes a jump in the initial
memory allocation for you apache proc

Caveat Lector:
Long Cleanups done inline on the Apache children can cause problems.
If you get a situation where the CleanUp takes to long OR you get
enough traffic to the page(s) which engage the CleanUp then you will
encounter a tipping point, and soon after your website will be almost
complete
It seems pretty clear the blank pages are from the apache children dieing
badly (hence the errors). I would make an educated guess based on the
malloc error that your ram is bad. Try running your app on a different box
and see if you get the same errors.

This is the list of stuff I usually start with when I get a problem
that doesn't seem to be tied to a particular code path.
* code path - perhaps a particular code path is only being exercised
rarely, and it has a bug
* forking - when child dies, all open descriptors in it's name space

The documentation alludes to the variable 'pwd_whereclause'. If this
variable is set it will be used in the passwd query. I would try and
set it per client so that the query gets an additional where clause:
SELECT pwd_field FROM pwd_table WHERE uid_field = user AND client = clientA

Could be many things. Maybe multiple hits to different Apache

I would not try to unify disparate configs into one unless each server
is actually going to service all the virtual hosts your

Whenever I creating shrink-wrapped software I always make packaging
and distribution part of the development, qa and testing process. All
packages for the platforms that we will be supporting. The reason I
do this is to cut down on the customer support overhead. I've found
you get less calls and
There are all kinds of problems that you'll encounter and have to solve if
you fork. I found it's better to call at(1) to start another seperate
process immediatly. If you need to pass data JSON worked really well for
me.

You can you use either pnotes or subpr
Does anyone if it's possible to fall through the default_handler
(decline?) to a PerlHandler?
What I want to do is issue a redirect if the file that was requested
is not on disk, and I don't want the extra stat due to an NFS mount.
Of course I can serve up the file myself, but it seems as though
