I have a PHP server running, with cron jobs etc... And once a day (between midnight and 3am), apache spawns one process that never ends. The server is a virtual server, so in a couple of days it eats up the whole memory.
Is there a way to figure out what is crashing ? What php script isn't finishing ? Or what url via apache was triggered ?
I have tried looking on the access logs, errors logs, but didn't find anything unusual.
