             Summary: Zeppelin gets stuck with java.lang.Thread.State: BLOCKED 
(on object monitor)
                 Key: ZEPPELIN-2724
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-2724
             Project: Zeppelin
          Issue Type: Bug
          Components: zeppelin-server
    Affects Versions: 0.7.2, 0.8.0
            Reporter: Sergey Mazin


We are using Zeppelin in 10+ active users environment. At least 2-3 times per 
day Zeppelin hangs with no errors in log files.

I checked Jstack and looks like Zeppelin is waiting for lock on some resource, 
which is locked by other thread.
