The virtual server that is running proxmox 1.6 is being hammered and I don't know where to start to bring the load down to normal levels. Our load average was around 1-2, with 384Mb or memory and 1 processor.
Today our users were complaining that they were not getting their e-mails from outside, and that when they did, it was 2 hours later.
I checked the machine, and the load average has been at 15 or higher. The mail queue is huge (1500+ messages). I gave the virtual machine 1Gb of memory fearing that it was thrashing the swap and gave it access to 2 processors, but the load remained the same and nothing changed (other than it's using now much more memory).
If I hit the flush queue option in the queue, the numbers reset and start queueing up again. Eventually I see errors from proxprox saying that it can't connect to postfix.
I see a bunch of proxprox processes with top (at times the whole top screen has these processes only).
Here's a sample line from top
17319 root 16 0 74024 52m 2776 R 27.3 5.2 0:07.31 proxprox
I changed the order of the dns servers in resolv.conf to see if it was dns latency that was causing this, but nothing changed.
Is there anything I can do to start troubleshooting the high load?
Thanks,
Alex.
