It depends on how your distributed enviroment works. 
If you have proxies for objects. And the proxy is garbage collected on
Server A it has to inform
the proxy on the other Server B, because this proxy may hold references
to other objects. 
This can result in a lot of communication between the servers. 

Other problems in distributed enviroments are that sometimes servers may
be down or not reachable. 

So distributed GC is not that easy ...
