Hi there,
I am having an issue with cyrus processes growing to use all of my cpus,
at which point I have to restart cyrus, because all other services on my
mail server grind to a halt. Below is my config file. Any ideas what may
be causing this? I noticed this behavior after the last cyrus update. I
am currently using cyrus 2.2.13-19+squeeze1, debian. I think my
processor should be plenty powerful for the mail load I handle.
thanks,
maria
