Routing

Continous BGP activity may result in increasing amounts of memory held

Symptoms: 
Memory increase occurs in 'BGP Router' process due to BGP path attributes. Memory used by this process increases constantly and so do the BGP path attributes while the number of routes does not increase.

Not sure why they don't call this a "leak" but apparently they have a different way to describe it.

Basically, if you use BGP, don't use SXJ as it will leak itself to death over a period of time, possibly as short as 4 weeks with full routes.
