Forgot to add, this was for lmtp, where the logs here aren't mentioning it, here's what the kernel says, task lmtp blocked for more than 120 seconds.

Hey there guys,
Here's what I found in the logs:

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.
