  Thanks for your idea - using die prevents it from coming up.  As I
mentioned, it is rather random so sometimes hard to verify.
My auto_prepend and auto_append have no value in  php.ini.  I'm
wondering why you suggested that?

If something was injecting code using the auto_append param, then you would not know about it, but it would still cause you issues. And by issuing a die or exit at the end of the code would show if it was your code or something running after all your script has completed.

Hi all,
I've been chasing around a memory allocation error for some time and
can't figure it out. It is somewhat random - I can run the script 3
times and then it will happen, or sometimes the first time.

It happens at the very end of a script, actually after the script has
finished running. I will see the following after the closing </html>

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to
allocate 494142432 bytes) in Unknown on line 0

Just previous to this my mem usage is 3772104

The script itself does some database work (deletes, inserts, selects)
but nothing very heavy and writes out an XML file. I use adodb 5.18, the
server is PHP 5.3.18 (this was updated recently) and it is a VPS on

As you can see, the memory limit is 256M so it's really high and I never
see that I'm using more than 4M. The error doesn't fall through my error
class - I'm assuming that's because it is happening after the script is

I am completely out of ideas on how to trap it or figure it out.
Any ideas would be appreciated!

Try adding exit or die at the end of what you know is the end of your
scripts. See if the problem continues.  Maybe at the very end of your
customer error handler.

If the problem stops showing up, you might want to look at your PHP
config to see if anything is setup in the "auto_append_file" section.
