Hi All,

One of our queue in rabbitmq got crashed and then when we tried to restart the rabbitmq it got completely crashed.

Attaching both the logs.

Please help us to find the root cause.

Thanks in advance.

You’re getting `{error,eperm}` all over the logs, that’s an OS error. Please check that your user still has permission to access the RMQ storage, if the disk is full and so on.

Hi Diana,

Thank you for your input.

We are running the rabbitmq from root user. So the permission can not be an issue here.

We are getting the below message in every 10 mili seconds.

Hi,

It is a permissions problem. And the log you shared now says "client unexpectedly closed TCP connection" so it's something external that keeps connecting and then terminating connections. RabbitMQ can't do anything about it.

Both symptoms are quite typical for antivirus or other security-related software that tries to restrict disk access and network connections. If you have such software installed - disable it (or make it not interfere with RabbitMQ).

Best,
