one of my servers only has one resource intensive (php) site and the rest are static sites...

all of a sudden it has started tripping (php error codes, php scripts not working, etc.)

why is this?

is there any way to prevent this from happenning..it is on a amd duron server with 512mb

Dont know a whole lot about php, but it could be just a badly written script

well its actually the new modernbill version

Did you just overwrite files??? Could be a permissions problem make sure all the permissions are set correctly.

What version of cURL are you running?
