>Any idea why APC (Or is it Litespeed) restarts every 1 hour and some minutes or so? Is that an issue or is it normal?
there are many reasons to cause litespeed restarting. for example, you host thousands of accounts/virtual hosts under litespeed or apache. modifying configuration of a virtual host will cause a litespeed restart. if only host a few virtual hosts, and configuration is fixed, you will see litespeed will run there for weeks/months without restarting.
