php query error Error while sending QUERY packet. PID=xxx

Background: Use the Yii2 command line mode to start a script to monitor the rabbitmq queue. When the queue has order information, perform query and update operations (equivalent to writing a query in a PHP file, update, and start using the command line)

Problem: There is no problem with monitoring at the beginning, but an error will be thrown every once in a while
