Celery + RabbitMQ stuck at mingle: searching for neighbors -

-

i encountered strange issue while trying system running on new machines.

os:

ubuntu 14.04.1 lts (gnu/linux 3.13.0-39-generic x86_64)

packages:

celery==3.1.13

django-celery==3.0.23

librabbitmq==1.5.2

broker:

rabbitmq "3.2.4"

after restart celery process gets stuck:

[2014-11-10 18:32:55,792: info/mainprocess] connected amqp://user:**@172.16.10.6:5672/vhost [2014-11-10 18:32:55,804: info/mainprocess] mingle: searching neighbors

tried find solution elsewhere. here found advice increase disk space available rabbitmq. checked docs , changed in rabbitmq.config file:

{disk_free_limit, {mem_relative, 1.0}}

now rabbitmq should have 6gb available, doesn't push celery ready state. tried configuring (as suggested) limit of open file descriptors in

/etc/default/rabbitmq-server

without effect. current rabbitmq status:

    [{pid,4131},  {running_applications,      [{rabbitmq_management,"rabbitmq management console","3.2.4"},       {rabbitmq_web_dispatch,"rabbitmq web dispatcher","3.2.4"},       {webmachine,"webmachine","1.10.3-rmq3.2.4-gite9359c7"},       {mochiweb,"mochimedia web server","2.7.0-rmq3.2.4-git680dba8"},       {rabbitmq_management_agent,"rabbitmq management agent","3.2.4"},       {rabbit,"rabbitmq","3.2.4"},       {os_mon,"cpo  cxc 138 46","2.2.14"},       {inets,"inets  cxc 138 49","5.9.7"},       {mnesia,"mnesia  cxc 138 12","4.11"},       {amqp_client,"rabbitmq amqp client","3.2.4"},       {xmerl,"xml parser","1.3.5"},       {sasl,"sasl  cxc 138 11","2.3.4"},       {stdlib,"erts  cxc 138 10","1.19.4"},       {kernel,"erts  cxc 138 10","2.16.4"}]},  {os,{unix,linux}},  {erlang_version,      "erlang r16b03 (erts-5.10.4) [source] [64-bit] [smp:4:4] [async-threads:30] [kernel-poll:true]\n"},  {memory,      [{total,46342000},       {connection_procs,290304},       {queue_procs,62864},       {plugins,458136},       {other_proc,13673776},       {mnesia,76376},       {mgmt_db,127808},       {msg_index,34384},       {other_ets,1100432},       {binary,5282744},       {code,19974306},       {atom,703377},       {other_system,4557493}]},  {vm_memory_high_watermark,0.4},  {vm_memory_limit,2503614464},  {disk_free_limit,6259036160},  {disk_free,2779140096},  {file_descriptors,      [{total_limit,924},{total_used,13},{sockets_limit,829},{sockets_used,9}]},  {processes,[{limit,1048576},{used,270}]},  {run_queue,0},  {uptime,4561}]

another thing: when stop celery processes supervisor no warm shutdown logged (actually - nothing logged).

could help?

i had same problem seems. check own answer own question here:

celeryd rabbitmq hangs on "mingle: searching neighbors", plain celery works

long story short:

sudo apt-get remove librabbitmq1

worked me.
