APAR status

  • Closed as program error.

Error description

  • Under some circumstances, when a File Gateway route is set to
create mailboxes dynamically, the add mailbox threads can
deadlock against each other in the JVM.

This is a race condition.  Some of the things that need to
happen for it to show up are:
1) File Gateway routes set up to create mailboxes dynamically.
2) Multiple messages being processed are trying to create the
same mailbox.

One of the symptoms you will see is an insert into the
MBX_MAILBOX table in the database that is not being commited.
