What should happen in the client when we detect arrhythmia? Do we blow up? Should we do this on the server as well? What is the behavior there if so?

On both sides it has to properly disconnect. In the server that will mean locks get released etc. on the client it means alex's new disconnect event will occur. Thing is, I didn't mean to assign this to you :-)
This was supposed to be assigned to tim. Sorry

Implemented health check between the L1 to L2, L2 to L1 and L2 to L2 in networked Active-passive.
