Although this might not be a RMS related issue maybe you have some hints.. In one of our shops the SQL Server (installed locally on the cash register) seems to hang from time to time. That means suddenly it cannot be accessed anymore. Not by the POS, not by StoreOPManager - not even by the administrator. We have to reboot the Register in order to make it work again. The Service is still running and the Eventlog doesn't show any problems. Also the Taskmanager shows 90% idle.
Any Ideas?
