I found that there is changes in the way monitoring information is
gathered. When I commented out in SunstoneServer.rb:
...
	filter[:uid] = opts[:uid] if opts[:gid]!="0"
...
it started to work. I think here we should correct this problem, which
is related also with code in acct/watch_client.rb:
...
        def filter_pool(filter)
             if filter[:uid]
                 filter[:uid]==0 ? (hosts = pool) : (return nil)
             elsif filter[:gid]
                 filter[:uid]==0 ? (hosts = pool) : (return nil)
             else
...
which also looks strange in elsif (it should look:
...
		 filter[:gid]==0 ? (hosts = pool) : (return nil).
...
I think in SunstoneServer.rb we should add
...
	filter[:uid] = opts[:uid] if opts[:gid] != 0
	filter[:gid] = opts[:gid]
...
Please take attention to "opts[:gid]" it is integer/numeric.
After those changes everything starts to work correctly (at least with
current logic).

P.S. Sorry for all this mess, probably it is better to attach patch file
for all changes.
