Hi all, Today I've observed a wrong behavior on our production environment that I would like to share with you because I think that it is wrong.
One "zookeeper server" was consuming about 25% of CPU and its log only shows lines like the following (as if it is was on some kind of loop): 2011-03-10 00:00:00,000 - WARN [NIOServerCxn.Factory: 0.0.0.0/0.0.0.0:2301:NIOServerCnxn$Factory@272][] - Ignoring unexpected runtime exception java.lang.NullPointerException After its restart, two "zookeeper client" instances received a Disconnected followed by a SyncConnected and several "NodeCreated" when those clients never set a "create" watcher since they only invoke getData o getChildren methods. That's why I think there is something wrong. Furthermore after a content modification all the "zookeeper clients" received a NodeDataChanged except for those which where connected previously to restarted server. The environment is: Solaris 10 + Zookeeper 3.3.2 + J6u17 64 bits. Please let me known if there is some kind of information that I could provide in order to perform some follow-up. Br, /César.
