If a Hazelcast instance that owns a CP session crashes, its CP session is not terminated immediately. Instead, the session is closed after CPSubsystemConfig.getSessionTimeToLiveSeconds() passes. If it is known for sure that the session owner is not partitioned away and actually crashed, this method can be used for closing the session and releasing its resources immediately.
