Moodle server crashing due to apache using too much memory?
HAs anyone else had this issue?
I am running moodle 2.5 on a virtual server with 8Gbytes of memory on ubuntu, having moved from running it on an old pc!
Anyway now when more than about 16 students log in moodle starts to struggle and then gives up, and I get errors "Out of memory: Kill process 5458 (apache2)"
running top before the crash shows an awful lot of apache processes.
Is there a way to manage how apache manages its memory usage and amount of processes?
