karim hamed created ZEPPELIN-110:
------------------------------------

             Summary: Possible memory leak
                 Key: ZEPPELIN-110
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-110
             Project: Zeppelin
          Issue Type: Bug
    Affects Versions: 0.5.0
            Reporter: karim hamed


I believe there maybe some sort of memory leak in zeppelin. Any memory used by zeppelin while it’s running is never released 
For example, If I ran a notebook with 5 paragraph, each only having 'println(“hello”)’ and scheduled that in a cron job that runs every 3 seconds. I find that any memory it takes when the paragraph is ran is never released again. This happens until the memory is full and the interpreter crashes with an out of memory exception

Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x0000c7f68c300000, 3462681297  1023448, 0) failed; error='Cannot allocate memory' (errno=12)
