The root cause of the problem has been determined to lie with the apache2handler for PHP. It is not sufficiently up to date to function well with Apache 2.4 receiving pipelined requests. A patch for the most common setup has been developed, but it has not yet been integrated upstream.
I have also put in an enhancement request at https://bz.apache.org/bugzilla/show_bug.cgi?id=57756, for a configuration option that could provide a fallback for server administrator, because this may equally affect other Apache 2.4 add-on handlers that have not undergone rigorous testing for this use case. ** Bug watch added: bz.apache.org/bugzilla/ #57756 https://bz.apache.org/bugzilla/show_bug.cgi?id=57756 -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to php5 in Ubuntu. https://bugs.launchpad.net/bugs/1407990 Title: apache2.4 mod-php5.5 random segmentation faults in zend_stack_push() and zend_hash_find() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/php5/+bug/1407990/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
