Two days ago we started getting 503 errors and all of our websites went down on our server. It happens in the afternoon and was only able to be dealt with by restarting the litespeed service. Today I got about 100 emails from the server with the message:
LiteSpeed Web server ***** on ***** restarts automatically to fix 503 Errors
I had to disable litespeed and restart apache to get the websites back online.
What in the heck is going on? No updates to the server recently...No new software installed etc.
There are about 300+ lsphp5 processes from days/weeks/months ago that appear to still be running but not doing anything.
