Memory requirements to prevent out-of-memory killer for an Open edX running on a virtual machine

[El Services]

Hi,

I recently got an internal server error when 6 simultaneous users were online.

The error log was:

OperationalError: (2002, "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)")

OpenedX was running on 6GB-RAM Ubuntu 12.04 virtual machine.

I increased the memory to 32GB-RAM now. No changes were made to MySQL memory settings.(like innodb_buffer_pool_size setting)

Will this be sufficient for 30 simultaneous users?

Best,

Yuvaraj.
