   @jiazhai I think the issue here is related to apache/bookkeeper#1569.

   in the heap dump, you can see one of the PerChannelBookieClient retains a lot of items
in `completionObjects`, which they event weren't timed out because the race condition in apache/bookkeeper#1569
could cause NPE and IllegalArgumentException (all kind of runtime exceptions). 
   
   The suggestion here is to upgrade Pulsar to 2.2.0, which contains the bookkeeper fix.
