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.

 Hello,

I have a bizarre problem I'm hoping someone could give me some suggestions
with.

I have a couple of MP2 scripts running on a server, they are both similar in
use of modules and structure. Without any recent changes, one of the scripts
is producing a blank apache page on SOME requests.

It's not always the same function, it can happen to any of the function
calls contained in the script.

When the blank page happens there is nothing in either the access log or the
error log of that virtual host (like the request never made it that far).

In the default error log I will get something like

[notice] child pid 11497 exit signal Aborted (6)

Sometimes (but not always), I'll see

*** glibc detected *** malloc(): memory corruption: 0x09c120f8 ***

 There is also no consistency to the blank page, sometimes you hit the URL
and you get the content, sometimes you get a blank page, sometimes 1 refresh
on the blank page gives you content, other times it can take 3 - 7 refreshes
before the content comes.

I've been trying to pull apart my script piece by piece in the hopes that I
could at least narrow it down to some specific section but I'm not having a
lot of luck.

Any thoughts on how I could debug this better?

TIA!
