dovecot - Dec 2005 - 1.0alpha5: fcntl() locking problem

Hi,

My setup: Solaris 9, /var/mail is NFS mounted from another
Solaris 9 box, home directories and dovecot index stuff is
on local ufs filesystems.  I upgraded from alpha4 to a5 about
36 hours ago.  Dovecot is configured like so during the build:

VERSION=1.0.alpha5
CC=gcc CFLAGS="-g -O" CPPFLAGS=-I/opt/openssl/include
LDFLAGS=-L/opt/openssl/lib \
./configure --prefix=/opt/dovecot.$VERSION --with-ssl=openssl \
--with-ssldir=/opt/openssl/ssl  > configure.out

This afternoon dovecot basically locked up where a lot of 
people (including me) were getting:

imap(user): fcntl() failed with mbox file /var/mail/user: No record locks
available

for syslog messages, and their mailbox operations would fail.
In my case pine just closed the mailbox with an internal error.

I did a quick fix by stopping dovecot, killing all dovecot processes,
killing /usr/lib/nfs/lockd on the dovecot server, and restarting
lockd.

Ideas?  Suggestions?

Hello, 
maybe it's not a dovecot problem. We had once a similar problem
with NFS mounted home directories. This message appeared with
the directories mounted from one server. The others were ok
(all with Solaris 9).

It was something with the NFS server (I don't remember the exact
reason). Restarting the NFS server (or booting) should help.

This error comes from kernel, so Dovecot can't really help it. Either
your lockd broke, or there were too many locks being used (stale locks
maybe left lying around?).
