[jira] [Created] (HAWQ-200) Investigate AOSegfileStatus leak

Lirong Jian created HAWQ-200:
--------------------------------

             Summary: Investigate AOSegfileStatus leak
                 Key: HAWQ-200
                 URL: https://issues.apache.org/jira/browse/HAWQ-200
             Project: Apache HAWQ
          Issue Type: Improvement
          Components: Storage
            Reporter: Lirong Jian
            Assignee: Lei Chang


It is usual to encounter the issue of "cannot open more than 262144 append-only table segment files concurrently", even sometimes the number of the open segment files in the underlying query is less than 262144.

It is suspected that AOSegFileStatus might be leaked (not freed) in some circumstances.
