Hans, The purpose is to stall (MDS based) communication, with a node that has exited cluster, as soon as possible.
----------- Example: Assume a system with nodes named A,B,C and D. If the node D were to exit the system, then "AVNDs" on A,B and C would get a message saying "node D has left the cluster". This would cause invocation of "tipc_reset.h" in A,B and C nodes to disconnect them from D. The expected result is that the TIPC links towards D (viz A<->D, B<->D, C<->D) get immediately disabled. ----------- This feature is useful if the TIPC link tolerance (== link health-check timeout) is set to value higher than the default 1.5s. A higher TIPC link tolerance avoids unnecessary TIPC connection failures in scenarios where a temporary link failure (and its resolution) takes greater than 1.5s. Due to lack of a better link reset/disable support in TIPC, "tipc_reset.sh" uses a workaround of temporarily bringing down the link tolerance to a low value. Hope this helps.

I currently don't have tipc_reset.sh working since tipc-config is not in /opt/TIPC (and it will never be). But what is the purpose of this script? I can see it is used by avnd when a node has left the cluster.
