Description

If you look at catalogd memz, e.g. at localhost:25020/memz, it has a bogus breakdown. The catalogd does not use the MemTracker infrastructure since the vast majority of it's memory consumption is in the JVM.

Breakdown

: Total=0 Peak=0
  Untracked Memory: Total=0

Update: It is the same for statestored as well and apart from "breakdown" section, the "Memory consumption / limit" part is also redundant. Should remove both parts from the memz pages of both daemons
