Major Our test suite can report success even when the Apache server crashed. The test suite should detect httpd crashes and report failure, if only to alert people that the apache/MPM they are using may have bugs. I found this when running Subversion trunk@1646184 with Apache 2.4.7 with the 'event' MPM, on Ubuntu 14.04. There is a known issue with the 'event' MPM crashing in several 2.4.x versions, fixed in later versions (>= 2.4.10 ?).

Searching the error_log may be the only way to detect these crashes.
