WorkFlow Mailer notification test

[big]

Hi,
On R12.2.4 DB 11.2.0.4 On AIX
When we send a test, we will receive 2 notifications: PL/SQL and OA FrameWork.

Then we acknowledge both. They are sent back to application server. But they are not processed and in syslog of OS (AIX) we can see :

Feb 24 15:53:35 appservermail:info imapd[213647]: Killed (lost mailbox lock) user=user1imp host=appserver.mat.com

Why is it killed?  ( two mails for the same mail box)?

What do you advise me

Thanks.

See the following thread ->

http://erman-arslan-s-oracle-forum.124.s1.nabble.com/WorkFlow-Mailer-notifications-and-Test-are-not-received-td10930.html

There I said the following;

The cause seems like having multiple connection to the same IMAP account.
I suspected from having multiple inbound threads, but it seems you configured only a single thread for imap. So this is not the cause.
Ensure that, you are using that imap account only from one WF mailer.. Each IMAP account should be dedicated to a single EBS WF Mailer.. Don't use the same imap account on different EBS environments.
Ensure you are not connecting to that imap account from different agents, and IPs.. WF Mailer should be the only one using it.

If you check the things that I mentioned above and if you think that you are okay, then check the OS side and IMAPD side.. You may be considering upgrading imapd and stuff like that.

See -> https://bugzilla.redhat.com/show_bug.cgi?id=20206  , Bug 20206 - Lost Mailbox Lock in IMAP ** BUT YOU ARE USING AIX. SO THAT BUG IS NOT RELEVANT FOR YOU.. IF YOU COULDN'T SOLVE THIS ANY OTHER WAY, THEN YOU SHOULD THE IBM SIDE..
