NVRAM errors when saving configuration

I was working on a client switch (VSS, modular IOS 12.2(33)SXH or IOS 12.2(33)SXI — I forget at this point) and ran into the following error message when attempting to save the configuration:

VSS-SWITCH #wr mem
Building configuration…

% String too long to write to nvram (2113): : ios-base : (PID=16407, TID=15) : -Traceback=(s72033_rp-adventerprisek9-10-dso-b.so+0×203C00) ([37:0]+0×203E24) ([26:-9]3+0×2868B0) ([36:0]+0×286FB0) ([26:-9]5+0×278940) ([36:0]+0×2789FC) ([26:-9]0+0×3D26C8) ([26:-9]10+0×200478) ([37:0]+0×200A90) ([37:0]+0×2005D8) ([26:-9]3+0×2859F0) ([26:-9]0+0×3D73CC) ([26:-9]12+0×1E7F40) ([26:-9]3+0×290D4C) ([26:-9]13+0×3CD224) ([37:0]+0×3CD1FC)

I thought that it could be an IOS bug. After Googling the problem, I looked at the document http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCsd45386 (CSCsd45386), but this wasn’t the cause of the problem.

The problem was that modular IOS wasn’t installed correctly (oops — a show version or show issu state can quickly show whether or not modular IOS is installed correctly).

I used the directions at http://www.xpresslearn.com/cisco/switching/upgrade-to-a-modular-ios-image.

After installation, no worries!

Here’s what happened after installing modular IOS:

VSS-SWITCH#writ mem

This is another oversight that can occur — don’t overlook (forget about it, or assume that it’s been installed by someone else) the installation of the modular IOS!
