I have a php website running on lighttpd. I have around 15 to 30k visits daily. Now, in my PHP code, I have a lot of warnings generated by undeclared $_GET or $_POST variables.
Obviously these are not shown to the user so are all logged into lighttpd log tiles.
Problem is: every 3 or 4 days those logs get so big that basically take up all the space in the system and can't do anything else, sessions stop working, etc.
How can I prevent lighttpd from writing up all those warning messages?
