rabbitmq failed to start

[Alexandra Dávila]

Dear All,

I am using:

rabbitmqctl --version 3.8.2

erlang 22.2.7

in Ubuntu 20.04.1 LTS Virtual Machine.

I am having trouble with rabbitmq-server. I tried to restart the rabbitmq, but I got an error message:

a) sudo service rabbitmq-server restart

Job for rabbitmq-server.service failed because the control process exited with error code.
See "systemctl status rabbitmq-server.service" and "journalctl -xe" for details.

b) systemctl status rabbitmq-server.service

rabbitmq-server.service - RabbitMQ Messaging Server
Loaded: loaded (/lib/systemd/system/rabbitmq-server.service; enabled; vendor preset: enabled)
Active: activating (auto-restart) (Result: exit-code) since Thu 2021-01-07 16:06:37 CET; 7s ago
Process: 22496 ExecStart=/usr/sbin/rabbitmq-server (code=exited, status=1/FAILURE)
 Main PID: 22496 (code=exited, status=1/FAILURE)

It seemed that the server has died and tries to reconnect. Then I tried to stop it:

c) systemctl stop rabbitmq-server.service

(no message error)

d) Then I start but I got the same message error again

Job for rabbitmq-server.service failed because the control process exited with error code.
See "systemctl status rabbitmq-server.service" and "journalctl -xe" for details.

I attached the log file. There I observed that when I tried to start rabbitmq-server, I observed the following error message:

Line 37598

I hope someone can help me with this!

Seems like a syntax error at some config file.

Hi, 

Thanks!

But I am not sure about it, because it has been working until today. Would it make sense?

Thanks in advance,

Hello,

You can delete this file and re-try -

/var/lib/rabbitmq/mnesia/rabbit@alexandra-VirtualBox/quorum/rabbit@alexandra-VirtualBox/00000055.wal

Please note that by running RabbitMQ in virtualbox there are no guarantees as to when data is actually written to a physical disk. RabbitMQ uses the "fsync" call to write data but virtualbox does not actually ensure the data is written to disk.

Thanks,

Luke
