[Bug 62813] New: exiting prefork child doesn't clear request pool


https://bz.apache.org/bugzilla/show_bug.cgi?id=62813

            Bug ID: 62813
           Summary: exiting prefork child doesn't clear request pool
           Product: Apache httpd-2
           Version: 2.2.34
          Hardware: All
                OS: Linux
            Status: NEW
          Keywords: PatchAvailable
          Severity: normal
          Priority: P2
         Component: mpm_worker
          Assignee: bugs@xxxxxxxxxxxxxxxx
          Reporter: luhliari@xxxxxxxxxx

        Depends on: 43857
  Target Milestone: ---

The same issue occurs when worker MPM is used. Don't have reproducer or fix
yet.

+++ This bug was initially created as a clone of Bug #43857 +++

When a prefork child exits (either graceful, or chosen as an idle child to die)
- the last request's pool is not cleared.

Server pool cleanups can depend on request pool cleanups having been run.  An
example is APR reslist.  If the last request acquired a resource, relist
cleanup
will fail an assertion:

  httpd: misc/apr_reslist.c:157: reslist_cleanup: Assertion `rl->ntotal == 0'
failed.
