[f-nsp] Random ServerIron Crashes

[Chris Good]

Some years ago I had similar behaviour on one of our SI-400s with it swapping
onto the secondary management card.  The other SI in the HA pair didn't appear
to be affected if we made that one live so we assumed a hardware fault on the
resetting one.  We spent some time swapping management and line cards in and 
out but that didn't resolve it so it looked like it was the chassis/backplane.

I am afraid that I never managed to get to the bottom of it as I was migrating
to ADXs at the time so it was easier to rip and replace.  Mind you we've ripped
out the ADXs now as Brocade refused to accept a bug report for the SSL related
denial of service that I discovered.  So ended an 16 year engagement with
Foundry/Brocade.  Way to go Brocade!
