      Shutdown after an unclean restart may pause while recovering the index page file free list.
      It may be necessary to increase the 30s delay in the shutdown script via the environment variable:
      ACTIVEMQ_KILL_MAXSECONDS=300

    Description

      Unclean shutdown forces the free pages in the index to be recovered. This can take many minutes on large stores. The change in behaviour follows from the fixes for: ENTMQ-2114

      A rework fo the fix, to do the recovery work on the next clean shutdown is a better approach, trading availability against some temporary disk usage.

      Note the rework of: https://issues.apache.org/jira/browse/AMQ-6590

      A further improvement does free page recovery async at start such that clean shutdown is no longer impacted.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
