We have a report from a client running a pockebrowser application on MC17 devices. We have recent reports of devices displaying an error that is generated when a javascript function tries to write to the registry using generic.SetRegistrySetting.  The error thrown to the window.onerror function is: "Can't write setting " The application has been running on hundreds of devices for over a year and the registry entry may be updated several times a day on some devices, so it has been written sucessfully many times. Is there a limit on registry writes? or a possibility of a fragmentation problem?  In an instance of a write failure like this would a cold-boot to clear the registry be expected to resolve the issue?
