I am getting some
strange behavior on a 4 node cluster. When node dbs2 tries to connect to
the cluster, node app3 either kernel panics or ccsd and rgmanager crash.
Node dbs2 says that the heartbeats drop off and it goes to remove itself
from the cluster. I am curious why node app3 would crash, and what these SM
messages are. Also why node dbs2 would connect to the cluster, become
quorate, and then drop off and crash node 1. Has anyone seen this
before?
