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!
