[rabbitmq-discuss] {disk_free_limit, {mem_relative, 1.0}}

[Arun Rao]

The location of the parameter also matters, is your rabbitmq.config file
similar to this?

[
{rabbit, [
...
{disk_free_limit, {mem_relative,1.0}}
...
]}
].

Also setting this relative to memory sets really "low watermark". For
example, If you have 16G RAM and 100G Hard disk. Setting this relative to
RAM makes low watermark set at 16GB. This means that Publishers are blocked
when your available disk space approaches 84GB (100-16). So I set this
value to 0.1 and now publishers are not blocking in case of backup until
98.4 (100-1.6). HTH
