Hi Stevo Slavic, I hope you are experimenting with standalone server. Please see ZooKeeperServerMain#runFromConfig() to see how a standalone server can be started/shutdown. Also, you can refer ZooKeeperServerMainTest to see standalone tests.
Yes, ZKServer#shutdown is not releasing all the resources, instead it is only clearing. One reason I can see is - in case of quorum lost, before entering into the next leader election phase it will only clear out all the data structures maintained in its database by calling #shutdown. Server will keep the I/O resources in hand as re-establishing resources is again costlier one.
