Re: [jgroups-users] RpcDispatcher does not invoke remote method

Found the problem; actually there were 2...

1: a max_bundle_size of 100K exceeds the max datagram packet size 
allowed by UDP. I added a sanity check to master to throw an exception 
if this happens.

2: FRAG2 is enabled on the main stack, but on none of the fork stacks. 
If you move FRAG2 below FORK, things will work.
