A couple of memory leaks have been fixed in the management plugin since 
3.1.0. From the changelog:

25600 fix consumer record leak in the management database (since 2.2.0)
25629 fix memory leak in the presence of long-lived channels and
       short-lived queues (since 3.1.0)

So an upgrade is definitely advised.

Cheers, Simon
