OK - thanks for your help. I do use PHP and I don't want to crash. ;)

But - unless I keep MaxRequestsPerChild at no more than 10 the memory 
usage grows fast. Could I have a memory leak of some kind?

    

Holey Moley! MaxRequestsPerChild 10 ! Yeah, sounds like a nasty
memory leak there. What other modules are you using? What PHP
