Exim causing excessive load
My server is experiencing high loads today. I think it is Exim causing the problem because there are multiple copies running and all are taking resources.I have restarted Exim and the load does drop, but comes back. I also did a /scripts/Exim4 to reinstall.
I don't think it is a spammer. I have tail'ed the log and also checked the queue. While I might be wrong, it does look like normal.
Anybody have any idea of what the problem might be or where to start looking?
