Randomwalk question

[Josh Elser <jo...@gmail.com>]

In playing with the randomwalk test previously, I don't remember seeing 
the following error. I've seen it over 2k times on the monitor for each 
of my tservers:

Unable to start TServer
	org.apache.thrift.transport.TTransportException: Could not create 
ServerSocket on address hostname/IP:9997.

Question: who/what keeps trying to start my tservers? Is this just part 
of LongClean.xml? The only reference I could find that might be starting 
things was concurrent.StartAll, but I can't imagine it being invoked so 
many times in a short period.

maybe the concurrent test.  It stops and starts things.
