problems with imapd from potato

[beto@inalambrica.net (Alberto Brealey G.)]

i've been having repeated problems with potato imap server (from the imap
package). Sometimes, while you are working with your mail folders, the
daemon just drops the connection. The relevant line from syslog:

Jan 17 10:00:23 moon imapd[20791]: Killed (lost mailbox lock) user=alf
host=dns1.localnet [10.101.0.2]

i'm accessing the imap mailboxes from pine 4.21 running on a slak 7.2 box.
The relevan files on the potato box are:

imap			4.7c-1
libc-client4.7	4.7c-1
libc6			2.1.3-10
libpam0g		0.72-8

i'm using /etc/cram-md5.pwd for authentication.

any ideas?

TIA
