Modify 'default' apache2 rate-limiting?
I have a webserver where I have bots that ping (via url to a PHP page) the server continuously -- Many times per minute.
It seems that after around 3 days some kind of rate limiting / throttling. Which is fixed by a reboot.
I'm not sure how to look for the root cause of this, because I need to be able to let these bots ping the server all they want.
(My server is a "default" UBUNTU server where I followed the tutorial to install LAMP -- so I dont believe I have anything "special" enabled).
If it's not an apache thing, could it be a firewall thing?
