[c-nsp] "sh run" bug

[Arie Vayner (avayner)]

Dmitry,

You are most likely hitting CSCsd45386 "write mem generates error %
String too long to write to nvram" 

Symptoms: When you enter the write memory command, the 
following error message and a traceback are generated:

Router#wr Building configuration...
% String too long to write to nvram (2578):Compressed configuration from

3452120 bytes to 786685 bytes[OK] Uncompressed configuration from 786685

bytes to 3452120 bytes

Conditions: This symptom is observed on a Cisco router when the
configuration 
is saved after you have entered the parser config cache 
interface command.

Workaround: Disable the no parser config cache interface 
command.

It is fixed in the current versions of 12.2SB, 12.4 and 12.4T trains.

Arie
