lockers causing messages to bounce

Tue May 24 12:57:00 EDT 2005

Hello!

I've been running cyrus imap for several years. Last night I upgraded 
one of my two imap servers to version 2.2.12 (from 2.0.11). This morning 
one of my users received this bounced message (mailj is a cname):

---------------------------------------------------

The Postfix program

<jdyke at mailj.whoi.edu>: host localhost[127.0.0.1] said: 190 lockers (in 
reply
to end of DATA command)
-------------------------------------

...and this was in my syslog:

May 24 10:55:13 daedalus postfix/lmtp[16444]: [ID 197553 mail.info] 
39CAD25A5: to=<jdyke at mailj.whoi.edu>, relay=localhost[127.0.0.1], 
delay=0, status=bounced (host localhost[127.0.0.1] said: 190lockers (in 
reply to end of DATA command))

So far this morning I've seen about 90 of these in syslog. I also have a 
lot of entries like the following:

May 24 12:42:38 daedalus postfix/lmtp[17316]: [ID 197553 mail.info] 
7FFF6251C: to=<gjpackard at mailg.whoi.edu>, relay=localhost[127.0.0.1], 
delay=0, status=sent (236 lockers)

I'm running Solaris9, postfix 2.1.5, imapd 2.2.12, berkeleydb 4.3.27.

My lockers has been hovering around 220 most of the morning with around 
350 users connected. Asside from this everything is running fine.
