Is there any other place which your code is changing the memory_limit
parameter? I would assume this is unlikely, but sometimes even the
unlikely happens more than than it should!

Can you maybe strip the code down to a test case which causes the error?

Lastly, I do notice that you've got two different versions of PHP &
Apache installed on each OS, which could be the reason for the failure.
Maybe set up a VM or two to test things out. Have one VM with Solaris
and Apache/2.2.3-11 & PHP/5.2.8, and another VM with Apache/2.0.53 &
PHP/5.0.4 and see what happens. It could be that it's either Apache or
PHP or both causing the problems on your Linux system.
