Remote procedure call (RPC) (using php-amqplib) in PHP server crash

[Roberto Maiocco]

After 15 minutes from procedure startup ( without receving messages) the server procedure hangs with an error: any idea?

here a dump of the error

I've tried even with docker and the behaviour it's different but with the same result (rpc example is useless or teh library does'nt work as expectred) 

with docker the consumer seems to be active but if I try to send a message with the producer, this seems to wait for a never-retruning acknowledge

Most likely it's a purely network-level issue. I'd recommend checking RabbitMQ logs (any info about connections?) and/or tcpdump/wireshark to see what's going on between the client and the server.
