** [tickets:#405] ImplementerClear returns BAD HANDLE for the Applier OI when
IMMND restarts during switchover**
**Status:** review
**Milestone:** 4.4.2
**Created:** Fri May 31, 2013 05:39 AM UTC by Nagendra Kumar

Migrated from http://devel.opensaf.org/ticket/2656
When IMMND is killed when switchover in progress, the AMFD applier OI(i.e. the
STANDBY that is becoming ACTIVE) gets BAD HANDLE for saImmOiImplementerClear().
This results in the AMFD asserting and switchover failure.
Attached is the log and the assert information.

Standby AMFD registers as an applier. If the IMMND restarts the applier OI
gets exposed and a BAD_HANDLE is returned to AMFD.
Presently amfd tries to reinitialize with IMMND in a separate thread when
dispatch returns BAD_HANDLE. At the same time, in the main thread
ImmOiplementerClear?() is attempted as a part of switchover processing.
One possible solution is:
If the ImmOihandle? is zero and the implementerclear return BAD_HANDLE, AMFD
can ignore this. As per the current flow of AMFD, subsequently when it attempts
the ImplementerSet?, if the handle is still zero and implementerSEt() returns
BAD_HANDLE, AMFD can do a try again from the main thread, until the reinit_bg
thread completes.

Any solution to this failure case (coping with local immnd crash during
switchover),
should be just a special case of coping with local immnd crash during normal
processing,
plus I assume immnd crash during other use cases.

Can you please upload more syslog from both the controllers, so that we want
to see when the controller rebooted and rejoined, when TIPC link was down, etc.
It will also help us in 2657.
