[c-nsp] TCAM Errors on SIP-401 Engine 5 Linecard for E1 SPA.

[Henry Sarumpaet]

hi there,
not exactly same, but we  have SIP-200 with SPA-8XCHT1/E1 running 
without any problem.
this one with : 122-33.SRC2 ( IOS & pkg ) unfortunately our qos config 
not complex as you are.
furher diagnostic it might be usefull to check the output of : "show 
plat hard capacity qos"
my $0.2
