Hello,

	We still have problems with our updated dovecot servers... The problem 
now is that we are having errors like:

Jul  9 10:22:02 myotis31 dovecot: lmtp(15431, <user>): Error: Timeout 
(180s) while waiting for lock for transaction log file 
/var/indexes/<user>/.INBOX/dovecot.index.log
Jul  9 10:22:02 myotis31 dovecot: lmtp(15431, <user>): Error: 
+4YfCwKS+k9HPAAAmo+UlA: sieve: msgid=<4FFA8700.2080003 at um.es>: failed to 
store into mailbox 'INBOX': Internal error occurred. Refer to server log 
for more information. [2012-07-09 10:19:02]
Jul  9 10:22:02 myotis31 dovecot: lmtp(15431, <user>): Error: 
+4YfCwKS+k9HPAAAmo+UlA: sieve: script /home/pdi/88/185188/.dovecot.sieve 
failed with unsuccessful implicit keep (user logfile 
/home/pdi/88/185188/.dovecot.sieve.log may reveal additional details)

	in the .dovecot.sieve.log all we have is just:

sieve: info: started log at Jul 09 10:22:02.
error: msgid=<4FFA8700.2080003 at um.es>: failed to store into mailbox 
'INBOX': Internal error occurred. Refer to server log for more 
information. [2012-07-09 10:19:02].

	maildir are in a nfs storage, but indexes are in local disk. I don't 
know if the problem could be related with a some "specific" messages or 
something specific to the user, because we are having this problem only 
with a few users and the problem repeatedly happens when our mta tries 
to deliver the queued message.

	Any idea?
