Happy new year all,
I am using moodle 2.4 with more than 6000 users and 700 courses for university, I ve just installed moodle 10 months ago and it was running fine till couple of weeks ago when apache started consuming a lot of memory causing the service to be down. am running moodle on ubuntu linux, with a 4 cores processor and 6 GB RAM. I wanted to ask do we need a load balance to overcome this issue? i.e) we only have one server with database on, shall we separate the database to another server and let the application deal with it? or I dont need that?
Actually am not facing a slow system rather than a sudden stop of service when i got 3.68 GB ram out of 6 GB ram reache this limit the website does not open (down), But I am still able to access the server and restart apache then it starts working again.
php version 5.4.6-1
MySQL client version: 5.5.32
am running moodle normally not common gateway interface and my error log is fine
you quick response is highly appreciated
