Then I copy messages in a directory via Thunderbird, the log shows:

dovecot: Feb 20 12:12:27 Error: IMAP(dvtest): 
o_stream_send_istream(/mnt/mailcache/dvtest/MailDir/.test/tmp/1171969947.P22138Q3.ux-2s11-9)

- -or-

dovecot: Feb 20 12:09:42 Error: child 22134 (imap) killed with signal 11

and repquota /mnt/mailcache
dvtest    +-     616     600    1024  6days      20     0     0

The Thunderbird continues to copy other messages believing everthing is 
OK.

There is also this message on the screen (started via dovecot -F):
dm-1: write failed, user block limit reached.

Bye,
