RabbitMQ Free disk space is insufficient - rabbitmq

Question

I try to add a message to a queue with Java client but rabbitmq keeps me blocked.
Official documentation says at https://www.rabbitmq.com/disk-alarms.html :
When free disk space drops below a configured limit (50 MB by default), an alarm will be triggered and all producers will be blocked.
My disc space looks like this
So, I set the disk space in the config file:
disk_free_limit.absolute = 1000MB
but it does not increment it. Disk space still looks like above.
Also log file says this:

How can I increment disk space?
My setup:
OS: Windows 10
RabbitMQ: 3.9.12
Erlang/OTP: 24.2

Answer 1

The alarm is telling you that your server only has 50MB of space left on the disk which RabbitMQ is trying to write to.
The disk_free_limit setting doesn't control how much disk is allocated, it controls how much disk is expected - if you set it to 1000MB, the alarm will be triggered as soon as there is only 1000MB left, rather than waiting until there is only 50MB left.
Making more disk space available is the same as it would be for any other program:
Delete other things that are using up your disk space - e.g. make sure log files are compressed and deleted after a certain amount of time
Configure RabbitMQ to use a different disk or partition, if you already have one that's bigger
Install a larger disk if it's a physical host, or allocate a larger disk image if it's a VM

This issue will be fixed in 3.9.13
https://github.com/rabbitmq/rabbitmq-server/pull/3970
NOTE: the RabbitMQ team monitors the rabbitmq-users mailing list and only sometimes answers questions on StackOverflow.

Answer 3

I changed RabbitMQ version to 3.9.11. Now, it is fixed.
I guess, version 3.9.12 was the problem.
