Question about lmtp.lock

[David G Mcmurtrie]

We've installed cyrus imapd 2.1.17 on a 4-node Veritas cluster and we're
now testing it.  Our /var/imap filesystem is on a clustered filesystem.

We noticed that all of the lmtpd processes are just sitting in a blocking
fcntl() call waiting for a lock on /var/imap/socket/lmtp.lock.  When we
run this in a clustered environment, each lmtpd is consuming CPU resources
while blocking.  In a non-clustered ufs environment they do not.

Is there any reason that the lmtpd processes need to be serialized across
different nodes in a cluster?  If not, we'll just write these lock files
to local ufs space on each cluster node.

While I'm on the subject, what is the purpose of
/var/imap/socket/imap.lock?

Thanks,

Dave
