python - Clients keeps waiting for RabbitMQ response -


i using rabbitmq launch processes in remote hosts located in other parts of world. eg, rabbitmq running in oregon host, , receives client message launch processes in ireland , california.

most of time, processes launched, and, when finish, rabbitmq returns output client. but, sometimes, jobs finish rabbitmq hasn't return output client, , client keeps hanging waiting response. these processes can take 10 minutes execute, client 10 minutes hanged waiting response.

i using celery connect rabbitmq, , client calls blocking using task.get(). in other words, client hangs until receives response call. understand why client did not response if jobs have finished. how can debug problem?

here celeryconfig.py

import os import sys  # add hadoop python env, running sys.path.append(os.path.dirname(os.path.basename(__file__)))  # broker configuration # medusa-rabbitmq name of hosts rabbitmq running broker_url = "amqp://celeryuser:celery@medusa-rabbitmq/celeryvhost"  celery_result_backend = "amqp" test_runner = 'celery.contrib.test_runner.run_tests'  # debug # celery_always_eager = true  # module loaded celery_imports = ("medusa.mergedirs", "medusa.medusasystem",                   "medusa.utility", "medusa.pingdaemon", "medusa.hdfs", "medusa.vote.voting")
