Sounds like a different problem. I shut down and restart the pool regularly and the slave/s reconnect normally. Sometimes a slave fails to see the master due to some network glitch, and the only workaround is to reboot the slave after which the pool is reconstituted. You didn't mention the XCP version. My pool is at 1.6Beta2.
