Hi Vu,
this osafassert will never assert, no matter what values reply_dest or
isObjSync have,
if reply_dest is 0 then osafassert(!reply_dest will be true.
/Regards HansN

Hi Hans,
I don't think so. In some cases, reply_dest could be 0 and not equal to
cb->immd_mdest_id.
Regards, Vu

Hi Vu,
not a big deal, but you are wrong, as I mentioned, the osafassert is now
a nop as
"reply_dest == cb->immnd_mdest_id" are always true at the osafassert stmt.

ack, review only. One question below.

When IMMND restarts (e.g: OUT OF ORDER detection), it may get
message
from active IMMD which is originated from just-dead IMMND process.
In such case, we are in confused situation - messages come from
local IMMND, but not me (reply_dest != cb->immnd_mdest_id)!
This patch discards such messages, notify the case to syslog
instead of aborting the IMMND progress.

redundant as
if (reply_dest && reply_dest != cb->immnd_mdest_id)

[Vu] The check should be there, otherwise assertion could get failed when
reply_dest != 0 and isObjSync is FALSE.
