Well there could be many causes why you do not have the uptime you should have.



What about hardware? I have a desktop that crashes from time to time. It used to be reliable but I had been coming to the conclusion that CPU, mobo or one of the memory sticks had gone bad. This idea was supported by the fact the machine sometimes fails POST. But lately I was in the BIOS setup and I saw a warning that the 3.3V is low (only 2.9V). So when i have time for troubleshooting ill check it with a multimeter and see about repairing or replacing the PS. Not anxious to do that as its a pricey 1000W corsair that i bought for a tidy sum on ebay but needs must. Anyway, I recommend you run on a different but similar HW platform and see if your issue goes away.



Another thing that would concern me if running lots of heavy apps is memory overcommit. Not wanting to start any flame wars but i distrust present memory management strategies and the OOM killer fills me with dread, even though i only encounter it very rarely and usually because I did something silly like coding an unintentional fork bomb or whatnot. And maybe if you ensure your system has adequate swap it might help the issue?



Just throwing a few things out there. I am sure you can resolve the issue eventually!!



Kind regards,

Nick
