Update

Ok, so we still have hangs. The blog neppe.no (which uses a lot of memory for PHP) and ZFS are the culprits. I had to undo some "fixes" to have neppe.no working at all. Until we have neppe.no using less memory, or more memory in the machine, we are going to have some occasional hangs. When the hangs happens, sometimes processes die. Because of this I have extended the monitoring on Totem to also check things like the mail queue length, and that Amavis/Postgrey are up and running. Should help to keep things up and running, and mail flowing.
