Description Tom Donovan 2007-11-14 10:16:01 UTC 
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.

Believe I'm seeing this on 2.2.15 during idle cleanup

httpd: misc/apr_reslist.c:159: reslist_cleanup: Assertion `rl->ntotal == 0' failed.

fix committed to trunk in r942897; I'll propose for merging back to the 2.2.x branch shortly
