what is your apache's mpm? worker or prefork?
Our site sometimes also rise similar error(like glibc detected ... in
error log ) under worker mpm.

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!
