%SYS-3-CONFIG_NO_PRIVATE: No space remaining to save private config
When I attempt to copy running-config to startup-config, I get the above error message. There is plenty of space in Flash. When I look up the message in the error message decoder, it says it is most likely a bug. I am wondering if there is a work around, short of switching IOS versions. Thanks!

I recommend implementing service compress-config if you haven't done it already:
