trashed databases after disk full situation

[Rodrigo Ventura]

Hello all,

I'm experiencing serious problems whenever there is an accidental disk full 
situation. I see two kinds of messages in syslog: the first one concerns the 
seen database, for instance:

Jul 21 09:39:54 omni imap[1133]: DBERROR: skiplist 
recovery /etc/imap/user/m/mflorencio.seen: ADD at 1FB0 exists
Jul 21 09:39:54 omni imap[1133]: DBERROR: 
opening /etc/imap/user/m/mflorencio.seen: cyrusdb error

what happens is that all mails become unreadable forever... I have to delete 
rge seen database.

the second one is, for instance:

Jul 21 10:47:07 omni lmtpunix[27618]: DBERROR db3: 5 lockers

what does it mean? is it possible to be expurious lock files? Please advise.

The cyrus version is 2.2.13 configured with
./configure --prefix=/usr/local/cyrus --with-duplicate-db=skiplist 
--with-sasl=/usr/local/cyrus --without-snmp

Can I switch the database backends to more realiable ones?

Cheers,

Rodrigo
