Iirc - the crash logs reported a cache corruption, and the 20 seconds
were spanning tree settling down - will ask my colleague in 2 weeks
when he gets back from holidays. Dont forget however - we are running
an old release on these boxes - ?sxi6/ sxj is current?  - and it only
happened after more than 1 year uptime. Not being an ISP means we can
get away with running older software longer.

We did open a tac case but unfortunately were not in a position to
replicate the problem.
