Buffer leak in PAM mbox

PAM mbox is a mechanism for 
NRP and NSP to communicate. 
There are special I/O buffers 
allocated for PAM mbox. These 
I/O buffers decrease and 
eventually become exhausted. 
When this happens, 
communications cease between 
NRP and NSP.

None.

NRP-2 GE<->GE back to 
back with no auto nego, not 
able to recover link.

GE interfaces of the NPR2 are 
connected back to back with auto 
negotiation turned off. Initially 
the connectivity works fine. 
However, when one of the GE

shut, the connectivity breaks. 
With auto negotiation off, the
