I don't see anything special in the logs.
No error message.

If i delete the dovecot.* files from the user home dir (index files i
guess) the index is recreated on login and all works fine.

Dovecot version: 1.0beta3.
I've just upgraded to 1.0beta5.

mmap_disable=no (default)
lock_method = flock (default)

I will change the mmap settings, what about the lock_method ?
Which one is better for nfs ?

Will this solve the corrupt dovecot.* index files (the ones which
already have problems) ?
