PHP Fatal Memory Errors

[dmwcashy]

We have a very busy site which runs great, we tried installing eAccelerator but starting getting lots of PHP errors about memory, like the following

Fatal error: Out of memory (allocated 786432) (tried to allocate 7350 bytes) in xxxxxxxxxxxxxxx.php(47) : eval()'d code on line 13

We have tested all scripts and the maximum script usage is ~10mb, This is not down to the PHP.ini memory setting as whatever this is set to has no effect on this issue.

We disabled eAccelerator and had no issues for 3 days solid, enabled it again and had errors within an hour.

We run on Windows 2003 Server, 4GB Ram.

Any ideas would be helpful as the product is good, and very useful.

Thanks

Also like to say it is installed as a Zend extension, as we could not get it to load as a PHP extension.
