child pid ### exit signal File size limit exceeded (25) - Apache

This error indicates that Apache is trying to handle a file which exceeds the maximum permitted filesize. I needed to fix this quickly this evening on an Apache box, but I have proper rotation on all access and error logs, so couldn't work out where the sink was.. Eventually it turned out to be the rewrite log.

Don't let this happen to you. Be sure to rotate all apache's logs properly, otherwise you essentially leave your Apache installation open to DOS attacks. It might take a lot of requests to create 2GB of Apache rewrite logs (and in this case it did!), but on a heavily SEO'd site with a high Rewrite Log Level value in Apache, it *will happen sooner or later.
