[rabbitmq-discuss] Connection blocked by "flow" for more than 600 seconds

[Choo]

Hi All,

I'm newbies to RabbitMQ, and wonder if you could help suggesting on the
issue I'm facing while implementing PoC environment.

RabbitMQ 3.1.5, Erlang R16B01 on RHEL, 2 servers in Ram+Disc mode cluster,
memory 128 GB each, the application is very fast pacing - publishing and
subscribing a lot of data from queues (up to 100 tps).

After running application for a couple of minutes, the connection reports
"blocked", and waiting does not make any good as it blocked for more than
600 seconds.  And happens all the time.

10.95.212.10:51961 -> 10.95.212.12:5672	750.270197	flow
10.95.212.10:51962 -> 10.95.212.12:5672	754.216011	flow
10.95.212.10:51963 -> 10.95.212.12:5672	510.589429	flow
10.95.212.10:51964 -> 10.95.212.12:5672	425.485488	flow
10.95.212.10:51965 -> 10.95.212.12:5672	441.14789	flow
10.95.212.10:51966 -> 10.95.212.12:5672	163.170952	flow
10.95.212.10:51967 -> 10.95.212.12:5672	3.059871	flow
10.95.212.10:51968 -> 10.95.212.12:5672	426.142116	flow
10.95.212.10:51969 -> 10.95.212.12:5672	766.418793	flow
10.95.212.10:51970 -> 10.95.212.12:5672	768.384091	flow
10.95.212.10:51971 -> 10.95.212.12:5672	162.18209	flow
10.95.212.10:51973 -> 10.95.212.12:5672	68.669802	flow
10.95.212.10:51974 -> 10.95.212.12:5672	754.631573	flow
10.95.212.10:51975 -> 10.95.212.12:5672	754.435615	flow
10.95.212.10:51976 -> 10.95.212.12:5672	68.507427	flow
10.95.212.10:51979 -> 10.95.212.12:5672	441.270346	flow
10.95.212.10:51980 -> 10.95.212.12:5672	441.121977	flow
10.95.212.10:51983 -> 10.95.212.12:5672	68.646785	flow
  
And for status:

{memory,
     [{total,3859855376},
      {connection_procs,88174824},
      {queue_procs,244276080},
      {plugins,985632},
      {other_proc,265771096},
      {mnesia,2432752},
      {mgmt_db,101090840},
      {msg_index,592688264},
      {other_ets,588080336},
      {binary,1939595920},
      {code,19746169},
      {atom,703377},
      {other_system,16310086}]},
 {vm_memory_high_watermark,0.85},
 {vm_memory_limit,115011143065},
 {disk_free_limit,1000000000},
 {disk_free,91763609600},

Any suggestion would be very welcome.

Thank you, and Best Regards,
Choo
