[c-nsp] [cisco-bba] 7204VXR(NPE-G1) running c7200-jk9s-mz.123-14.T3.bin

[Oliver Boehmer (oboehmer)]

Mark,

to me, this looks like side-effects of the memory leak, i.e. you're
running out of memory causing all kinds of things. Do you get malloc
failures in the logs? What is the TAC case# so I can take a look?

I do wonder about the PARSER-4-BADCFG message. What is the trigger for
them? Do you do some config via tftp or similar (copy tftp
running-config)?
