Kafka version is 0.8.1.1. On taking a thread dump against one of our servers in Kafka Cluster, i see lot of threads with message below:
"SOMEID-9" id=67784 idx=0x75c tid=24485 prio=5 alive, parked, native_blocked, daemon -- Parking to wait for: java/util/concurrent/locks/AbstractQueuedSynchronizer$ConditionObject@0x100a13500 at jrockit/vm/Locks.park0(J)V(Native Method) There are multiple threads with the message "Parking to wait for" with the same objectId- 0x100a13500. Does this imply that the consumer threads are stuck or just sitting idle? Thanks, Prashant To learn more about SuiteWorld, visit www.netsuite.com/suiteworld.
