I removed dotlock some time ago (using director) and switched to:

lock_method = fcntl
mail_fsync = always

With "count" as quota backend I get a lot of these errors on the 
director:

imap-login: Error: proxy(xxx at xxxx.xxx): Login for xxx.xxx.xxx.xxx:143 
timed out in state=2 (after 30 secs, local=xxxxx:58478): 
user=<xxxx at xxxx.dk>, method=CRAM-MD5, rip=xxxx, lip=xxxxx, TLS, 
session=<pTl0UTlAV8VWNF5+>

on the server:

imap(xxxx at xxxx.xxx): Warning: Locking transaction log file 
/mnt/nfs/xxxx.dk/xxxxx/indexes/.INBOX/dovecot.index.log took 32 seconds
