(FunctionClauseError) no function clause matching in RabbitMQ.CLI.Core.Memory.formatted_watermark/1 #2964
Description
Hello,
I think there is a bug in rabbitmqctl parsing of relative memory watermark:
/usr/lib/rabbitmq/bin/rabbitmqctl -q status
Stack trace:
** (FunctionClauseError) no function clause matching in RabbitMQ.CLI.Core.Memory.formatted_watermark/1

My config file is the following:

It used to work fine on branch 3.7.x but not 3.8.x, and I already looked at the GIT history and saw a lot of changes related to memory watermark parsing but I already have all of them.
