Hey there guys,

We noticed this as the server wouldn't stop overloading, reaching 150+ load, we had to reboot it. It's not the first time we see this, and kill -9 PID wouldn't do anything to the processes, at all.
Any idea guys? We're stuck here. I've tried to increase the RAM allocation for dovecot, hope it helps.
