Description pioklo 2012-05-24 14:09:02 UTC 
Hello !
Simple bad rewrite can cause that apache use huge amount of memory and server hangs.

apache    7231  7251 48.1  130 17.0 5504108 4217176 ?     Rl   15:59   0:24 /usr/sbin/httpd -k start -DSSL


Our customer put some rewrite in .htaccess like the following

RewriteEngine On
RewriteBase /
RewriteRule ^tlumaczenia-przysiegle/tlumacz-przysiegly-bulgarskiego-([0-9a-zA-Z|-]+)/?$ http://supertlumacz.pl/tlumaczenia-przysiegle-$1 [R=301,L]

When we access the page apache start to use 100% of memory

Comment 1 William A. Rowe Jr. 2018-11-07 21:09:34 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.
