I'm currently in the process of building up a web application. However, I occasionally run into an issue where "usr/sbin/exim_tidydb /var/spool/exim wait-remote_smtp" suddenly jumps up to 99% cpu and prevents other processes of my application from running.
From what I understand Exim is a webmail service, however there are a very limited amount of emails being sent out from this application (certainly not enough to cause this).
What's going on and how can I prevent this from happening?
BTW: I'm running Centos v.5 on dedicated hardware with standard apache at the moment.
