My Linux OpenSuse server all the sudden became bogged down, it had to be rebooted, could not ssh in or use the Vmware to open get to the consol.
Cause: Switching automatic backups on (enable) slows the server immediatly. The CPU is used up by apache2 processes that increase with this option turned on.
The backups are not even setup to run now, they run on the weekend so why does switching the auto backup opion to enable causes an issue immediately?
More details:
Site Admin > Courses > Course request > backups > automatic backups>
Using Moodle 2.3.3+ (Build: 20121220)
Plenty of free disk space
Only CPU spikes up to 100%, not RAM
Changing it back to "Disable" resolves the issue and the server goes back to normal.
See screen shot
Thanks!
