[c-nsp] Strange error with older VIP2

[Bill Wichers]

One of our older routers (an old 7576) dropped a BGP session today and
reported some errors via syslog as below. It's a VIP2-50 with a PA-FE-TX,
and has a single FE link to a peer. I'm thinking either the VIP2 or the
PA-FE-TX is dying, but I'm hoping someone can maybe help me interpret the
log entries so that I know what to swap out with spares if only one or the
other of the parts is bad. Right now the router is reloading the VIP about
every 12 hours with the same basic error. Any ideas are appreciated.
