RabbitMQ hanged up

  • 772

I have single RabbitMQ 3.6.1-1 installed on CentOS 7.2.1511, with Erlang R16B-03.16.el7. Today I cleaned it up:

rabbitmqctl stop_app
rabbitmqctl force_reset
rabbitmqctl start_app

It worked for some time and now (maybe, after 8 hours of data processing) it doesn't respond to application requests and status check:

# rabbitmqctl status
Status of node 'rabbit@RabbitMQ-Server' ...
^C
Session terminated, killing shell... ...killed.

Also, I have a lot of messages in /var/log/rabbitmq/startup_log. These messages are repeating in infinite loop: http://pastebin.com/38AXyw4n

There are nothing in other logs:

# ls -lS
total 6481664
-rw-r--r-- 1 root     root     2365375398 Apr 30 21:34 startup_log
-rw-r--r-- 1 rabbitmq rabbitmq          0 Apr 30 14:18 [email protected]
-rw-r--r-- 1 rabbitmq rabbitmq          0 Apr 30 20:45 [email protected]
-rw-r--r-- 1 root     root              0 Apr 30 14:18 startup_err

What's wrong with RabbitMQ? How I could restore it back to working state?

  1. Seems like it was some inconstistency between versions of RabbitMQ and Erlang. I've installed Erlang package from RabbitMQ maintainers, after that logging and AMQP handshakes began working as expected. 

    systemctl stop rabbitmq-server
killall epmd

yum remove rabbitmq-server
yum remove erlang
yum autoremove

wget https://www.rabbitmq.com/releases/erlang/erlang-18.3-1.el7.centos.x86_64.rpm
wget https://www.rabbitmq.com/releases/rabbitmq-server/v3.6.1/rabbitmq-server-3.6.1-1.noarch.rpm
yum install erlang-18.3-1.el7.centos.x86_64.rpm
yum install rabbitmq-server-3.6.1-1.noarch.rpm
