Hello,
Using virtual mailbox plugin and all of a sudden started getting these. Deleted the indexes from ~/Maildir/virtual/Inboxmail and all was good again.
dovecot: 2009-05-10 10:05:44 Error: child 26607 (imap) killed with signal 11 (core dumps disabled)
Inboxmail/dovecot-virtual: virtual/All inthread refs x-mailbox INBOX
All/dovecot-virtual: * -Archive/ -Drafts/ -Trash/ -Trash/* -Deleted* -Junk* -Spam/ -Sent* all
I have had this happen 2 or 3 times now, I thought maybe the first couple were flukes from messing with the dovecot-virtual files, then sometime between last night and now this started to give those errors. I am taking a guess that is it is some kind of indexing issue since just deleting those seems to fix it. Not sure what other info I could send, turning mail_debug = yes didnt give any useful info in dovecot.log
