Hi, I did several tests with current dbmail cvs with trace level 3 for imapd. While copying lot of messages to dbmail suddenly no new connection was possible, imapd didn't respond any more.
The last sign of life was: May 16 14:55:37 geht-schon dbmail/imap4d[3825]: dbpgsql.c,db_free_result: trying to free a result set that is already NULL! May 16 14:55:37 geht-schon last message repeated 5 times May 16 14:55:40 geht-schon dbmail/imap4d[3825]: COMMAND: [317 append "INBOX/wd" (\Seen) {1985953}] The client copying the mails finished copying without problem though (took until 15:10). I found several error messages in the logs: - tons of this one: dbmail/imap4d[25968]: dbpgsql.c,db_free_result: trying to free a result set that is already NULL! - quite a lot of these: dbmail/imap4d[25968]: dbpgsql.c,db_query: previous result set is possibly not freed. - some of these (they belong together): dbmail/imap4d[25977]: db_add_mime_children(): unexpected end of data dbmail/imap4d[25977]: db_start_msg(): error adding MIME-children dbmail/imap4d[25977]: db_fetch_headers(): succesfully recovered erroneous message 2961 - some of these dbmail/imap4d[2661]: ChildSighandler(): got signal [13] "trying to free ..." always happens on APPEND and UID for example. Ilja the Outlook (Express) problems are fixed as far as I've tested it, thanks a lot! Thomas -- http://www.tmueller.com for pgp key (95702B3B)
