> "Memory Total" is currently a sum of availableMB, allocatedMB, and reservedMB.
> It seems that the term "availableMB" actually means "total memory", since it doesn't get decreased when some jobs use a certain amount of memory.
> Hence, the Memory Total should not include allocatedMB, or availableMB doesn't get updated properly.
