[Dovecot] some errors on 1.1.3

[Karsten Künne]

Hi,

we recently upgraded dovecot from 1.0.5 to 1.1.3+latest patches. After the 
upgrade I saw some errors in the logs and I'm not sure whether they're a 
cause for concern. Our setup is 2 servers running openSUSE 11.0 and a NetApp 
Filer as storage backend. Following is the config:

protocols: imap imaps pop3 pop3s
login_dir: /var/run/dovecot/login
login_executable(default): /usr/lib64/dovecot/imap-login
login_executable(imap): /usr/lib64/dovecot/imap-login
login_executable(pop3): /usr/lib64/dovecot/pop3-login
login_max_processes_count: 512
max_mail_processes: 1024
verbose_proctitle: yes
first_valid_uid: 100
mail_location: 
maildir:~/.Maildir:CONTROL=/var/mailctl/%n:INDEX=/var/mailctl/%n
mail_nfs_storage: yes
mail_nfs_index: yes
mail_executable(default): /usr/lib64/dovecot/imap
mail_executable(imap): /usr/lib64/dovecot/imap

      mode: 384
plugin:
  quota: fs
  fts: squat
  fts_squat: partial=4 full=4

The errors we're seeing are:

Oct  1 07:39:27 host1 dovecot: IMAP(user1): Invalid transaction log size 
(83856 vs 83160): /var/mailctl/corey/.INBOX/dovecot.index.log

Interrupted system call

It only seems to affect a handful of users and they didn't complain so I 
assume they didn't see any negative effect on the client side. But it would 
be nice if somebody could explain shortly whether these errors are serious 
and we should be concerned or if they are harmless.
