interface went down, IP ran out of memory when recalculating the best routes

to use. This was exacerbated when the high memory usage triggered the BGP

backoff mechanism which in turn disabled the BGP peers, which caused IP to

recalculate even more routes. The switch eventually rebooted due to memory

exhaustion.

This issue has been resolved by improvements to memory allocation and IP route

queuing, and by enforcing limits on the number of IP routes.
