Hello Igor:
The locker number does indeed continue to grow, in the 500s one time even
into the 1000s. My next problem is this, I have it installed 2.1.12 from
the tar source, what steps should I take to install the new version? Should
I download the source, or is it possible for me to use the rpm on RH8? I
saw the readme from the rpms and it said not to install it if you have
previously tried to install from source. What should I backup prior to
trying to install either the source or the rpm?
If you do not change berkeley api, the upgraded cyrus imapd should just
work (this does not mean you should not backup) I install everything
from sources.

Thanks,

Upgrade cyrus will fix your problem.

Q: I'm getting messages in imapd.log like:
Sep 11 17:23:55 ogg lmtpd[773]: DBERROR db3: 16 lockers
Sep 11 17:23:55 ogg lmtpd[1409]: DBERROR db3: 17 lockers
Sep 11 17:23:56 ogg lmtpd[1508]: DBERROR db3: 9 lockers
Sep 11 17:23:56 ogg lmtpd[776]: DBERROR db3: 9 lockers
What's wrong?
A: Nothing is wrong. These messages are logged whenever Berkeley
db encounters lock contention, but isn't necessarily a problem by
themselves. This is especially likely when you have an empty or small
duplicate delivery database and are receiving a large volume of
e-mail.
Berkeley db 4.0 has a bug where the number of lockers isn't
decremented properly, causing this number to be unreliable.

Hello:
We have a Cyrus IMAPD server version 2.1.12 running on a RH 8 server.
All
is working find up until last week, now we are getting increasing errors
as
follows:
Nov 7 22:36:33 antar lmtpd[1057]: DBERROR db4: 50 lockers
The number before lockers keeps going higher and higher until eventually
the
server stops receiving pop and imap connections. After a restart of the
server, it starts over again. My question is, how can I stop these, and
why
after a reboot does it reset down to 1 again? I have read a bit in the
archives and it seems that this has something to do with Berkley DB and
that
updating to newest version of Cyrus should fix this, is this correct? If
so, what are the necessary steps to install the latest version,
preserving
the existing system, users, messages, etc.
In addition, previous version was not installed with the RPM, can you let
me
know where to find the RPM for RH8?
Any light you can shed is appreciated.
Regards,
Steve
