We have an installation of Moodle 2.4 on a VPS with 1Gb RAM.
We have expected to have around 15-20 concurrent users, but with only 2 or 3 concurrent users, the server crashes due to memory use overload. We have followed almost every recommendation in the Performance recommendations page.
Do you think we need a RAM memory upgrade on the VPS server? Is anybody experiencing this problem on Dreamhost? Could anyone recommend us another hosting that has been reliable for a Moodle installation?
Thanks in advance,
