[jira] [Created] (GEODE-9295) entry idle expiration threads may hang

Darrel Schneider created GEODE-9295:
---------------------------------------

             Summary: entry idle expiration threads may hang
                 Key: GEODE-9295
                 URL: https://issues.apache.org/jira/browse/GEODE-9295
             Project: Geode
          Issue Type: Bug
          Components: expiration
    Affects Versions: 1.13.2, 1.13.1, 1.13.0, 1.13.3, 1.14.0, 1.15.0
            Reporter: Darrel Schneider


GEODE-7921 in 1.13 introduced this issue. When processing a message used by entry idle expiration to find out when an entry was last accessed on any member of the cluster it now checks for a null cache, region, and entry. If any of them are null the message simply returns. The problem is that the expiration thread that sent this message waits forever for a reply. So unless the member that found a null leaves the cluster, the expiration thread will be hung waiting for a reply that will never be sent.

The fix for this is easy. We just need to send a reply of zero when we find a null.
