[c-nsp] problems with 6500 and syncing sup config.

[Thomason, Simon]

Hey Ken,

Lodged a job to tac just in case as this is a core device but I did get a few off list emails which pointed me in the right direction.

Also be VERY careful about this if you're running Modular code.

Modular code actively reads/writes to the flash filesystem periodically,
and not sure if it touches the NVRAM during normal operation.

Sounds like the nvram: on the standby sup is full and/or corrupted.

Try:

dir nvram:
dir slavenvram:

...and see if anything obvious presents itself.

It's possible you'll need to:

erase nvram:
erase slavenvram:
wr mem

...but I'd be cautious about doing that. I'm not sure what else it might

kill (e.g. SNMP ifindex persistence, SSH keys, etc.)
