Can't Save Running Config in 1760 Router

%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!

You have 2759 bits free, not much.

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

The configuration is stored in NVRAM, not Flash.

Please post the show file systems output.

Oops! Sorry, I got confused because someone had written a config to flash. Here are results of the show file system:

service compress config

Thanks to both of you! When I realized the config really had gotten too big to save in NVRAM, I deleted some unused access-lists and was able to save the config.
