I have recently had a problem on our server with the load spiking. The database processes seem to be fine and I don't see any accounts that seem to be agreesively using bandwidth. All the accounts seem to be normal. Does anybody have any recommendations on how to find the source of the problem? Perhaps I'm missing something here.
Is there a way to run a top process check for exim to see which account has the most exim processes running?
To check how many exim processes are running, execute
It will show you all the processes along with exim processes with it's CPU and RAM usage. If you see a long list of exim processes, check the mail logs to see if anyone is sending out spam emails OR your domain is targetted
tail -f /var/log/exim_mainlog
It will show you the incoming/outgoing emails that are flowing to/from the server.
