Keep in mind that this is problematic http payload transaction (layer 7 problem), not just layer 2 or layer 3 problem.
From my understanding; if the problem is the layer 1, then it must affect ALL application and not just one. It is like layer 1 problem directly causes layer 7 problem without affecting layer 2 to layer 6 at all.
What I don't understand is how improper PVC rebuild in the frame relay cloud might only affect one specific http application?
In addition, other http applications were not affected; just one specific http application.
Weird?
