Fwiw, here's the Zookeeper log entry for a graceful shutdown of the Solr replica: 2014-12-12 15:04:21,304 [myid:2] - INFO [ProcessThread(sid:2 cport:8181)::PrepRequestProcessor@476] - Processed session termination for sessionid: 0x34a1701a1df0037 And here's the Zookeeper log entry for a non-graceful shutdown via EC2 stop or terminate of the replica: 2014-12-12 14:19:22,000 [myid:2] - INFO [SessionTracker:ZooKeeperServer@325] - Expiring session 0x14a1700c19c003f, timeout of 15000ms exceeded 2014-12-12 14:19:22,001 [myid:2] - INFO [ProcessThread(sid:2 cport:8181)::PrepRequestProcessor@476] - Processed session termination for sessionid: 0x14a1700c19c003f There was no hang in the graceful shutdown.
