Unexplained heavy loads lately on Cyrus servers

[twk]

We have 8 IMAP servers at NCSU; 4 of them are running Cyrus 1.5.14 under Solaris 
2.6, 4 are running 2.1.5 under Solaris 2.7.

In the last 2 weeks or so, both sets of servers have been running under a much 
larger load than usual, which does not seem to correlate with any know events 
(significantly more accounts, network problems, etc.). We have added more memory 
to some of these systems, and sometimes an additional drive just for swap.

I'm wondering if anyone has noticed changes in the behavior of any of the 
mainstream email clients (Netscape Messenger, Outlook Express, Outlook, etc.) 
that may be inadvertantly generating more load on the server.

Thanks,
Tom
