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

Wed Oct 9 00:09:05 BST 2013

Hi Matthias,

Thank you for suggestion.  I have adjusted the file_descriptor as below:

 {erlang_version,
     "Erlang R16B01 (erts-5.10.2) [source-bdf5300] [64-bit] [smp:40:40]
[async-threads:30] [hipe] [kernel-poll:true]\n"},
 {memory,
     [{total,3176523080},
      {connection_procs,122464344},
      {queue_procs,1248670152},
      {plugins,748048},
      {other_proc,72262776},
      {mnesia,2432784},
      {mgmt_db,10208},
      {msg_index,289132896},
      {other_ets,191916432},
      {binary,1208094960},
      {code,19312210},
      {atom,703377},
      {other_system,20774893}]},
 {vm_memory_high_watermark,0.85},
 {vm_memory_limit,115011143065},
 {disk_free_limit,1000000000},
 {disk_free,92036349952},
 {file_descriptors,
     [{total_limit,10140},
      {total_used,4907},
      {sockets_limit,9124},
      {sockets_used,376}]},
 {processes,[{limit,1048576},{used,3980}]},

So, it seems like memory is enough, file_descriptor is enough, and disk_free
should still be ok.  But the connection is still blocked.  But good thing
is, the block duration seems shorter.

10.95.212.10:42336 -> 10.95.212.12:5672	blocked	0	flow	17.306112
10.95.212.10:42338 -> 10.95.212.12:5672	blocked	0	flow	108.213992
10.95.212.10:42359 -> 10.95.212.12:5672	blocked	0	flow	36.799473
10.95.212.10:42360 -> 10.95.212.12:5672	blocked	0	flow	146.325601
10.95.212.10:42361 -> 10.95.212.12:5672	blocked	0	flow	53.655967
10.95.212.10:42374 -> 10.95.212.12:5672	blocked	0	flow	121.259312
10.95.212.10:42375 -> 10.95.212.12:5672	blocked	0	flow	139.258805
10.95.212.10:42376 -> 10.95.212.12:5672	blocked	0	flow	137.210049
10.95.212.10:42377 -> 10.95.212.12:5672	blocked	0	flow	51.628542

Any other areas I should check?

Thank you and Best Regards,
Choo
