Hi Jon,
Thanks for your kind response. I see your point - one of the node having
very old kernel is a risk.
Atleast the TIPC link establishment part - There isn't much difference I
believe. I suspect this has to do something with either the host
environment or TIPC configuration.
I would like to share few observations on the tests I carried out with
different kernel versions.
TIPC compatibility between
1. 3.13.0-32 and 4.4.0-45 works fine .
2. 3.13.0-32 and 4.6.0-rc6 has issue similar to (3.2.0-29 <-> 4.6.0-rc6).
Coming back to the original problem (3.2.0-29 and 4.6.0-rc6) - Below I am
sharing TIPC message capture that happens forever without link getting to
stable state. Please help if this data will hint something on the TIPC link
fluctuations.
