[Dovecot] Errors in Dovecot 1.0.5

Thanks for the help. I am getting fewer errors in the log file now, 
after switching the indices over to local files, but they are still 
happening.

For example, this morning:

Nov  2 06:19:33 server2 dovecot: IMAP(x): Maildir 
/home/store4/x/.Garbage sync: UIDVALIDITY changed (1193995001 -> 1193996801)
Nov  2 06:19:33 server2 dovecot: IMAP(x): Corrupted transaction log file 
/var/dovecot/x/.Garbage/dovecot.index.log.2: invalid indexid (1193995001 
!= 1193998773)
Nov  2 06:19:33 server2 dovecot: IMAP(x): Corrupted index cache file 
/var/dovecot/x/.Garbage/dovecot.index.cache: indexid changed


Here is another from yesterday afternoon:

Nov  1 17:39:39 server2 dovecot: imap-login: Login: user=<x>, 
method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured
Nov  1 17:39:39 server2 dovecot: IMAP(x): Transaction log file 
/var/dovecot/x/.sent-mail/dovecot.index.log: marked corrupted
Nov  1 17:39:39 server2 dovecot: IMAP(x): Transaction log file 
/var/dovecot/x/.sent-mail/dovecot.index.log.2: marked corrupted
Nov  1 17:39:39 server2 dovecot: IMAP(x): Maildir 
/home/store4/x/.sent-mail sync: UID < next_uid (3 < 69, file = 
1193952487.P1105Q0M269080.server2:2,S)
Nov  1 17:39:39 server2 dovecot: IMAP(x): Disconnected: Mailbox
is in inconsistent state, please relogin.

All of this is with maildir stores accessed via NFS but indices are 
stored locally.

Is this normal? It seems like dovecot mostly continues and plays through 
it, but there are a lot of errors in the logs about corrupted files.

Thanks
Jeff
