Subject Re: Cluster hung after a node killed
Date Wed, 30 Nov 2016 20:20:35 GMT
Hi Val,

Killing the node that acquired the lock did not release it automatically and
leads whole cluster in hung state, any operation on any cache (not related
to lock) are in wait state. Cluster is not able to recover seamlessly. Looks
like a bug to me. 

I understand lock timeout can be error-prone, if configured correctly then
lock timeout can provide a second way of auto recovery in such failover
cases. Is there any way to configure timeouts on lock?

Explicit lock is one of the usecase we have, but Cluster auto recovery
during any change to cluster is the most important, so if these 2 not going
together then its a show stopper.
