Random SIGTERM & SIGHUP exceptions in infinite loop

[prasadpilla]

Every few hours/tens of mins or so I am seeing SIGTERM & SIGHUP exceptions popping up from get_packet method.

Here is the stack trace, can you please look into this? I dug into the code, it just fails in the queue pop method, so i couldn't figure out what's wrong there.

lib/mqtt/client.rb:436 pop lib/mqtt/client.rb:436 block in get_packet lib/mqtt/client.rb:435 loop lib/mqtt/client.rb:435 get_packet lib/mqtt/client.rb:404 get bin/mqtt_consumer:14 consume_messages bin/mqtt_consumer:26

Just figured this is probably nothing to do with the lib itself. Some process is sending SIGTERM. Thanks
