iApps are unable to reconfigure pools that have monitors associated with them.


Monitor change does not occur. GUI or tmsh might post an error similar to the following: Monitor rule not found.


Using tmsh or iApps in the GUI to re-configure the pool monitor (for example, changing the monitor from 'http' to 'none').
