<div dir="ltr"><div><div><div>Hello,<br><br></div>I am using rabbitmq server and python-kombu client library for RPC communication. It is observed that the client stops consuming the messages from the queue and all these messages remain unacknowledged. <br>
<br>We found the following link which is near to our problem. But, we observe that open fds are not greater that the max limit (1024). Anything else can lead to this situation?<br><a href="http://lists.rabbitmq.com/pipermail/rabbitmq-discuss/2014-May/036063.html">http://lists.rabbitmq.com/pipermail/rabbitmq-discuss/2014-May/036063.html</a><br>
<br>Following is the rabbitmq version.<br><br>[{rabbit,"RabbitMQ","3.0.2"},<br>                        {os_mon,"CPO  CXC 138 46","2.2.9"},<br>                        {mnesia,"MNESIA  CXC 138 12","4.7"},<br>
                        {sasl,"SASL  CXC 138 11","2.2.1"},<br>                        {stdlib,"ERTS  CXC 138 10","1.18.1"},<br>                        {kernel,"ERTS  CXC 138 10","2.15.1"}]},<br>
<br>The RPC client stack is as following. Looks like it is struck for some reason. Did anybody observe this issue?<br><br>cat /proc/12733/stack <br>[<ffffffff811a6609>] poll_schedule_timeout+0x49/0x70<br>[<ffffffff811a7d34>] do_sys_poll+0x424/0x4d0<br>
