I've noticed strange behavior on our throughput tests at one site.  Sometimes, the graph turn unidirectional - ie, one way stops working.  Sometimes, both ways will stop working.  The times are random.  Although the site is verified up by ping and passes traffic, however the throughput graphs vary greatly.  (We believe due to issues with this circuit)

I've only seen it do this in this one case.  It's almost like it gets angry that the speed varies vastly and gives up.  

Has anybody else encountered this?  Any ideas greatly appreciated.
