My web & name server runs out of memory from time to time, to the point where it's completely unresponsive to anything. At that point reset is the only alternative. (Or, as this is a virtual guest, I just say "virsh destroy").
But why this happens - I would like to know.
Sever things could be occurring. The first thing I notice is that you have many httpd processes running. This can be useful if you have many simultaneous hits. If you don't, you can tune the number of processes down
We've got a number of websites on one of our production servers, and they get hit moderately (it's not Amazon... but they are US gov't scientific research sites), and I think we've got 25 threads running, total, to server *all* of them. <snip>
From "top" (situation now): Mem: 1361564k total, 1264324k used, 97240k free, 8428k buffers Swap: 3014648k total, 64852k used, 2949796k free, 358676k cached
That doesn't look like a lot of memory.. Possible to add another .5G or so?
Ah! I missed that. Is it actually the case that your server doesn't even have 2G of RAM? That's a *real* problem. If you're not running it on a five year old desktop, you need to add - I'd say you shouldn't be running with under 4GB of real memory.
