[j-nsp] Odd behaviour testing failover

[Gordon Smith]

Hi all,

I'm seeing odd RE behaviour on an M20 while testing RE failover.
>From the log entries, I'm guessing that a snapshot of the current route
table entries gets tarballed and passed to the second RE to use while
the control plane re-establishes adjacencies with other devices.

Problem is, the tarball can't be found by the RE, and transit traffic
fails until it re-meshes.

Has anyone come across this before?
If so, how do I get this to behave? Graceful failover is enabled on this
box (JUNOS 7.3R1.6)

Also seeing kernel page faults in the logs on the backup RE during
failover. Hard disk failing?
