Post disconnect - reconnect Reply with quote

I see this in the log file - we are running on NT - connecting to an Oracle database on Unix.
Is this normal - or is something set up incorrectly.
Thanks.

Hope, this doesn't look good. It looks like the daemon process keeps hanging after successful connection to the database because of a database lock or it takes too long to retrieve a message or message attachment causing the DB Mail to "think" the daemon is hung.

Try the following
1. Check if DB_MAIL.MAIL_ATTACH table is locked. If yes, kill locking processes.
2. If 1st is no help, check what you have in DB_MAIL.MAIL_ATTACH table. If there are really large attachments delete them from the table.
3. If 2nd doesn't help delete everything from that table (TRUNCATE TABLE DB_MAIL.MAIL_ATTACH)
4. If 3rd doesn't help purge database side message queue
CALL DBMS_PIPE.REMOVE_PIPE('DB_MAIL')
5. If 4th does not help try restarting computer running DB Mail server and if even that doesn't help try bouncing the database.
