I've been getting this error repeatedly: "The process “mysqld” was terminated because the system is low on memory". I have a blog running on WordPress and a forum running on XenForo In the log, I see that too many php processes are there. This usually happens once or twice in the day, and the load spikes so much that the server goes out of memory and mysqld terminates. As suggested in the famous thread here, I tried checking the access logs in case this increased load is caused by increased traffic, but that does not seem to be the case as traffic is not high when this occurs. The load is very high, there are too many php processes open, there's the WordPress's index.php with a high CPU usage in the WHM's daily process log. Even the mysql tables report some tables as crashed, but I do have a weekly cron job that repairs them, apart from the InnoDB ones I think. Can anyone suggest what could be the problem? Have attached some logs.
