推荐答案
上述nginx错误表明该问题与fastcgi(php-fpm)有关.
The above nginx error indicate that issue is related to the fastcgi(php-fpm).
在/etc/php5/fpm/pool.d/www.conf上启用"catch_workers_output"之后在php5-fpm.log上找到了相关的错误.现在了解该问题与AMQP模块有关.
After enabling the "catch_workers_output" on /etc/php5/fpm/pool.d/www.confGot the relevant error on php5-fpm.log. Now understand that issue is related to AMQP module.
