What does this apache error mean?

Whenever i run certain pages on my site (made in php) I get this error

[Sun Mar 23 19:12:31 2008] [notice] Parent: child process exited with status 128 -- Restarting.

I think its related to perhaps using too much memory or something? theres a lot going on in the page, and it hasnt started until today (lots of data was added to the mysql database today)

I want to go in and find ways to optimize the code to fix this problem (since it seems to be related to a signifcantly larger database) but without getting any errors besides this I can't really figure out where he issue is coming from., here is the whole snippet from the log...

Quote:
[Sun Mar 23 19:22:15 2008] [notice] Child 5316: Starting 250 worker threads.
[Sun Mar 23 19:25:14 2008] [notice] Parent: child process exited with status 128 -- Restarting.
[Sun Mar 23 19:25:15 2008] [notice] Apache/2.0.55 (Win32) PHP/5.1.2 configured -- resuming normal operations
[Sun Mar 23 19:25:15 2008] [notice] Server built: Oct 9 2005 19:16:56
[Sun Mar 23 19:25:15 2008] [notice] Parent: Created child process 1756
[Sun Mar 23 19:25:16 2008] [notice] Child 1756: Child process is running
[Sun Mar 23 19:25:16 2008] [notice] Child 1756: Acquired the start mutex.


anyone have any ideas how I might identify the choking point? I've tried commenting out parts of the page that I think would use a lot of power, but theres a lot of lines to try this on and I feel like I might not even be close.

A Google search indicates that it could be related to preg_match or mysqli_* and that upgrading PHP may resolve the issue.

i saw those results, but most of those seem to be related to people on php4, and also I do not use preg_march or mysqli_* in my code (however mysql_* is used, but not menitoned in any results)
