Summary0000641: apache server stops responding to simple requests from ab.exe
DescriptionA stress test run as

  ab -c1 -n4000 http://slamain/hello-db.php

never completes. apache stops responding after some number of requests - typically between 500 and 3500. The failure is not permanent. If one waits a bit and retrys, apache will responds to some number of new requests before it again stops responding. It appears that whatever resource is causing the failure mode is released after some period of time.

hello-db.php is a simple select query using the mysqli interface.

Similar tests

  ab -c1 -n10000 http://slamain/hello.php
  ab -c1 -n10000 http://slamain/

which eliminate mysql from the processing chain run to completion which implies that the issues is either in the mysqli php extension or the mysql daemon.
