In the past 5 days, I've had one of my servers lock up atleast 15 times so far which has caused about a dozen hours of downtime. The datacenter said I may need a RAM upgrade, but I've been monitoring the server almost every 30 minutes and I've never seen a high cpu load of memory usuage. I've had them check out the logs for me and there is nothing out of the ordinary. The lockups seem to be happening roughly at the same times every day, however sometimes a random one does happen. Do any of you have any ideas on what can be done to this thing?
