I’ve recently setup a Bytemark 1 CPU VM using Symbioisis Jessie. I’ve put two smallish online shops on the server so far and it seems to be running well from a front of house point of view. However I’m occasionally getting emails such as this:
*** Error: Cannot allocate memory - /etc/symbiosis/monit.d/apache2 2>&1
*** For help, type: /usr/sbin/symbiosis-monit -h
Does this email suggest I am running out of RAM?
At the moment the server is running with a load average of 0.10, 0.16, 0.13.
Memory used is 81.3% of 1.0GiB
Is there anything I can do (apart from upgrading) to free up some RAM?
