RabbitMQ virtual host error when starting service

问题


I've had a RabbitMQ server running for months. This morning I was unable to connect to it, my applications was timing out and the Management client was unresponsive. Rebooted the machine. Applications are still timing out. I'm able to login to the Management client but I see this message:

Virtual host / experienced an error on node rabbit@MQT01 and may be inaccessible

All my queues are there but can't see any exchanges.

I hope someone can help me figure out what going on. I've looked at the logs but can't find any good hint.

Here a part of the log:

I figured out what was going on. Someone on my team (me) was creating an unprecedented amount of connections to RabbitMQ. For each connection a file handler is created to one or more files, not sure which. The OS (Windows in my case) has a file handler limit, not sure what the limit is, but when reached, an error is thrown. This corrupted the virtual host (/) and I had to delete it and create it again. Good thing this wasn't production, because then all the messages would've been gone.

I opted to recreate the vhost which resolved the issue for me.

Clearing the data in transient msg_stores & queues didn't work for me in my scenario. Since data loss wasn't an issue for me.

For me, I was trying to install management plugin (rabbitmqadmin) and it failed in rabbitmq-delayed-message-exchange. So I downloaded rabbitmq-delayed-message-exchange from JFrog Bintray and updated my plugins folder, stopped and started rabbitmq service. This action, courrupted the database.

To fix it,

  1. Stop Rabbitmq service

  2. I went to %APPDATA%\RabbitMQ\db and cleared the data in transient msg_stores & queues folders. e.g. C:\Users\bharath\AppData\Roaming\RabbitMQ\db\rabbit@js-mnesia\msg_stores\vhosts\6ZOILVXV632BBEWZY4TBABTPP\msg_store_transient

  3. Removed the rabbitmq-delayed-message-exchange from rabbit@js-plugins-expand folder

  4. Removed the data in transient msg_store & queues from RABBIT~1-upgrade-backup folder

  5. Went one folder back and removed the plugin name rabbitmq-delayed-message-exchange, from enabled_plugins file

  6. Start the rabbitmq service

It worked!!!

Note: Only try this if data is not important, as it will get cleared or you can restore it from backup.
