I guess, there was some process that tried using your nvram and failed to get access or the process got hang.......and now when you are accessing it you are not able to read the nvram contents.....................not sure, i am just thinking it may be like that.......

Was there any crash happened on your switch afterwhich you have not rebooted it ? crash can be even a memory allocation failure......this might be the case mostly....... I guess there was a memory allocation failure happened on your switch..........if yes, then reboot is required and IOS upgrade.

A reboot might work i guess, but before doing that have all required precautions ready to bring up the switch incase if it fails.
