Summary: Incorrect PIDFILE prevent httpd restart
Product: Apache httpd-2 Reporter: Louis Benoit <louisbenoit>
Component: CoreAssignee: Apache HTTPD Bugs Mailing List <bugs>

Attachments: Contains error log, conf and service init

Description Louis Benoit 2013-03-06 21:54:19 UTC
Created attachment 30026 [details]
Contains error log, conf and service init

This situation was encountered when all the following conditions were met:
(1) The number of allowed thread for a process (ulimit -u) was smaller than the maximum number of configured thread specified in the configuration file.
(2) The number of simultaneous HTTP request was greater than the limit imposed by ulimit -u

This caused the main thread to exits but the child thread are still running. So the PID in the PIDFILE is not the correct one and the service "stop" does not work.

This was reproduce using Apache Benchmark: for example "ab -n 200 -c 200 http://..."  when "ulimit -u 32" was inserted before the deamon start in /etc/init.d.httpd.
Comment 1 William A. Rowe Jr. 2018-11-07 21:08:41 UTC
Please help us to refine our list of open and current defects; this is a mass update of old and inactive Bugzilla reports which reflect user error, already resolved defects, and still-existing defects in httpd.

As repeatedly announced, the Apache HTTP Server Project has discontinued all development and patch review of the 2.2.x series of releases. The final release 2.2.34 was published in July 2017, and no further evaluation of bug reports or security risks will be considered or published for 2.2.x releases. All reports older than 2.4.x have been updated to status RESOLVED/LATER; no further action is expected unless the report still applies to a current version of httpd.

If your report represented a question or confusion about how to use an httpd feature, an unexpected server behavior, problems building or installing httpd, or working with an external component (a third party module, browser etc.) we ask you to start by bringing your question to the User Support and Discussion mailing list, see [https://httpd.apache.org/lists.html#http-users] for details. Include a link to this Bugzilla report for completeness with your question.

If your report was clearly a defect in httpd or a feature request, we ask that you retest using a modern httpd release (2.4.33 or later) released in the past year. If it can be reproduced, please reopen this bug and change the Version field above to the httpd version you have reconfirmed with.

Your help in identifying defects or enhancements still applicable to the current httpd server software release is greatly appreciated.
