I'm running Apache 2.4 (64bit) on a Windows server. It also uses MySQL 5.7 on the same server.
It has been very, very slow recently to come up, but when I look at the access logs, there are very few connections. I do see some attempts to get at phpmyadmin and other scripts (none of which exist) but not hundreds of those requests.
When I looked at the memory httpd and Mysql were consuming, they were both very low and steady:
#tasklist
httpd 50,003 K
mysql 205,000 K
Restarting mysql made no difference in performance or memory. But after restarting httpd, it now takes 39,000 K in memory and the site is now responsive again.
I've looked in the logs and don't see anything out of the ordinary. So how do i determine what is making the site so non-responsive?
EDIT I don't know if it will help, but I'm going to try this fix: ( mentioned here: https://superuser.com/a/627251/223518 and here: https://stackoverflow.com/a/21033620/857025 )
Add the following to httpd.conf and restart httpd:
AcceptFilter http none
AcceptFilter https none
