Subject [jira] [Created] (FLINK-1465) GlobalBufferPool reports negative memory allocation
Date Sat, 31 Jan 2015 11:13:34 GMT
Robert Metzger created FLINK-1465:
-------------------------------------

             Summary: GlobalBufferPool reports negative memory allocation
                 Key: FLINK-1465
                 URL: https://issues.apache.org/jira/browse/FLINK-1465
             Project: Flink
          Issue Type: Bug
          Components: Local Runtime, TaskManager
    Affects Versions: 0.9
            Reporter: Robert Metzger


I've got this error message when starting Flink.
It does not really help me. I suspect that my configuration files (which worked with 0.8 aren't
working with 0.9 anymore). Still, the exception is reporting weird stuff
