Description
We have a 4 nodes cluster where we deploy an application using granular cache; fail-over is introduces by stop&start of each node in sequence;
We observed that restart takes longer than usual: ~3minutes (used to be ~13sec);
Each node is configured as follows:
embed-server --server-config=standalone-ha.xml if (outcome != success) of /subsystem=jgroups:read-attribute(name=default-stack) /subsystem=jgroups/channel=ee:write-attribute(name=stack,value=tcp) else /subsystem=jgroups:write-attribute(name=default-stack,value=tcp) /subsystem=jgroups/channel=ee:write-attribute(name=stack,value=tcp) end-if # doubled number of credits use by MFC and UFC between 7.4.x and 8.0.x - but this value is too high for the test environment /subsystem=jgroups/stack=tcp/protocol=UFC:map-put(name=properties, key=max_credits, value=2m) /subsystem=jgroups/stack=tcp/protocol=MFC:map-put(name=properties, key=max_credits, value=2m)
The issue was, most probably, caused by a recent JGroups upgrade;
