Thank you very much for your reply, Noel,
Firstly, posting the same message with a slightly modified subject wont get you any answers any sooner, please refrain from doing this, it only gives you a bad name and may have the opposite affect to one you desire.
Yeah, typical rookie move by posting twice...didn't see my post, so went into the dovecot list setting for my account to adjust it to get a confirmation, and then sent the message again. Really stupid, and I apologize.
Generally when lodging requests for help, it pays to use the latest version of software, 1.1.2 is old.
Definitely will be doing this, but just wanted to get some information on the locking issue first.
mbox over NFS ? That is asking for trouble, mbox is *not* NFS safe, you are best changing to maildir which is.
Yeah, this is definitely wrong. Everything is in maildir format on the mailstore. Question is, why would this even be working at all if it's wrong in the config? The sql connection string has maildir defined in it, so, I'm wondering if that might explain it. Also, the indexes are not local which I believe has been the recommendation. Also Lockd appears to be enabled on both sides.

Hello All,
We are struggling to find a solution to a problem we are encounteringwith a load-balanced email setup. Currently, we have a Coyote loadbalancer, and 3 Postfix/Dovecot nodes that then get their information from a mysql database. The problem is that after a couple weeks, we start seeing NFS locking issues occur, which then takes email completely down, requiring a site visit to basically do an interactive mode reboot to shut off NFS so that we can remount the filesystem again. We have our mailstore on an Aberdeen NAS which is accessed over NFS v. 4.
Not seen this before, but we use Foundry LB's and NetApp filers. Coyote Is BSD based isn't it... How is your setup, you are not running the NFS mounts through the LB as well are you? I would hope they are on a separate private LAN
Dovecot version 1.1.2

Here's the relevant mysql string:
If the queries work at all, there's nothing wrong with them.
mbox:/NFS1MAILDIR/mailSysV2/%d/%u:INDEX=/usr/local/mail/indexes/%d/%1n/%n
