Randomwalk question
Josh Elser 2013-12-21, 02:13
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

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.
