Hi,
I just updated Cyrus Imapd on our somewhat old mailsever (dual-Xeon, but
8 years now, running gentoo linux) from 2.3.16 to 2.4.12
(options USE="berkdb kerberos pam replication sieve snmp sqlite ssl tcpd
-afs -mysql -nntp -postgres")
There is no murder and I also could drop sqlite, if better.
After the flawless update, restarting generated a huge load. I believe I
never had a load of> 50 any time before.
It even gets "/var/imap/socket/lmtp] timed out while sending MAIL FROM"
on local delivery of mails.
This is cyrus.conf:

# do not delete this entry!
recover cmd="ctl_cyrusdb -r"
# this is only necessary if using idled for IMAP IDLE
# idled cmd="idled"
}
# UNIX sockets start with a slash and are put into /var/imap/socket

# add or remove based on preferences

I have backups of the old packages, but I'man not shure if this will
work anymore.
Any ideas please ? My bloodpressure can't stand this...

How many mailboxes on the system? Took us about 2 hours to come down
from loads over 500 after the upgrade with 10,000 active user accounts.
