Hmm ... i can add a 'me too' ... i'm running cyrus 2.0.16 on a free webmail
service and in the last few months the loadavg was jumping high enough for
the sendmail to stop accepting connections. Now i managed to move the MTA to
frondend MXes, but the load didnt drop as much as i expect it would ... it's
still hovering around 5. Since cpuload is about the same, this must be
related to some increased i/o activity.
Only half a year ago this same box was humming nicely with approx the same
nubmer of users ...
