Not silly at all.

I have turned off ipv6 support on all servers. The SynchronizationMain establishes a connection with the DAS, but still hangs:

tcp 208312 0 192.168.100.31:11777 192.168.100.33:4848 ESTABLISHED 3691/java


After shutting down the NodeAgent I also deleted the instance directory to force a complete rebuild (probably not a good move).

This time I get the following exception:

The max heap for the domain is set to 768MB. There is 2GB allocated to the VM.
Does this look reasonable or should I increase the heap further?

I think the next thing to try is start with a clean install of the DAS and node agent.

Would there be any merit in moving to a 2.1 build?

Thanks for taking the time.
