Cannot write configuration on Nexus

One of my customers told me that he can’t save configuration on Nexus 7000 switch. It has been working for over 6 months with no problems.

switch1# copy running-config startup-config
Configuration update aborted: another request for config change is already in progress

It looks like a CSCtj44206 bug. In this case software switchover is not a solution as this request will be refused by system due to configuration lock. Solution, except full chassis reload, is performing hardware switchover by removing active supervisor from chassis. This will unlock configuration and let you perform ISSU to latest NX-OS where this bug is solved.
