just write a shell script with a endless loop something like this:
#!/bin/sh
while [ 1==1 ]; do
testClusterServer -e $*
done
with the -e option the clusterServer exists on disconnection.

if you want to do some more advanced things like changing the
clusterServer resolution layout whatever you have to write some kind of
service that starts the clusterServer with different parameters, if not
the shell script solution works fine.
