Hi, We are running 2.3.12 with the cyrus-skiplist-locking-rework-2.3.12.diff and cyrus-skiplist-nested-transactions-2.3.12.diff patch. I am writing some scripts to manage our mailboxes and hit some kind of bug. I created a mailbox cyrustest@xxxxxxxxxxxxx and when i try to delete a mailbox I get: BYE Fatal error: Internal error: assertion failed: cyrusdb_skiplist.c: 771: db->is_open We are also using delayed delete I also see the mailbox in the delayed delete hierarchy. mail7.UGent.be> lm user/cyrustest@xxxxxxxxxxxxx user/cyrustest@xxxxxxxxxxxxx (\HasNoChildren) mail7.UGent.be> lm DELETED/*@mail.ugent.be Now I delete the mailbox through imap. Now we see the deleted mailbox: mail7.UGent.be> lm DELETED/*@mail.ugent.be DELETED/user/cyrustest/4BD6B651@xxxxxxxxxxxxx (\Noselect \HasNoChildren) But original mailbox is still there mail7.UGent.be> lm user/cyrustest@xxxxxxxxxxxxx user/cyrustest@xxxxxxxxxxxxx (\HasNoChildren) The mailbox in the deleted tree is reserved: mail7.UGent.be> dm DELETED/user/cyrustest/4BD6B651@xxxxxxxxxxxxx deletemailbox: Mailbox is currently reserved No permissions set mail7.UGent.be> lam user/cyrustest@xxxxxxxxxxxxx mail7.UGent.be> sam cyrus x user/cyrustest@xxxxxxxxxxxxx cyrus@oeral:~$ echo $? 141 cyrus@oeral:~$ Restarting cyrus deletes the reservation, so I can deleted the mailbox in the deleted tree, but the original mailbox is still there. Any pointers on getting this fixed would be appreciated!
