Bug #66694 [NEW]: php-fpm is crashing when using eventport

From: eugene at zhegan dot in Operating system: Solaris 11.1 PHP version: 5.4.25 Package: FPM related Bug Type: Bug Bug description:php-fpm is crashing when using eventport Description: ------------ php-fpm is crashing when 'events.mechanism' is set to 'port'. It doesn't crash on first request, it can process some, however, the crash is imminent and my installation dumps cores like 1 per minute (this server is used by ~50 developers). When set to 'events.mechanism = /dev/poll' php-fpm stop to crash.
