GC overhead limit exceeded

[杨定裕]

Hi, all
When My adapter send large data to APP, adapter app occurs a error like
this:
Maybe the memory is limited and  the following processing is slow?

How can configure file in a real cluster.
I found that it is complex in a 20 nodes to create the topology.

And How can i remove a application in a cluster?

I saw s4-0.3 has a configure file "clusters.xml", but s-0.5 has not.
