Recently my VPS has been hitting max memory and crashing CPanel, HTTPD and pretty much everything else running on the server. I've searched and searched and can't find anything that's changed, even the number of users hasn't increased (if anything in the recent day's it's decreased!). I genuinely cannot see why over the last few weeks my memory used % is rocketing through the ceiling. On some occasions the CPU is maxed out with the memory, others it's just the memory. The strange thing is that there's only a handful of people connected to my forum and nothing else. It's certainly not demanding stuff, I can't work out why my VPS is dying. It's got to the stage where if I don't check my VPS every hour or two I find it's down and I'm losing members of my website because of this I need help if anyone's able to suggest anything? Where can I start looking? I've checked Cpanel and WHM, I've checked VZPP but all they say is privvmpages is maxed out. While typing this I've just restarted my entire VPS via the VZPP control panel (using reboot option) and the second it's restarted, the memory's at 100% again rendering my entire website unavailable. What's going on? Nobody's able to connect and this is getting more than annoying. I genuinely can't see why the demand has changed, there are less users and it's the same vBulletin processes but since a few weeks back the memory and occasionally CPU is just maxing out and dying taking me plenty of time restarting and trying to find faults that don't seem to exist. Help?
