[c-nsp] RES: Odd error after Interface flap [GSR/Engine 5]

[Leonardo Gama Souza]

I have seen the same messages recently on several slots after TE tunnels flap, but they caused a lot of issues (FIA errors, CEF disable and so on).

The version is 12.0(33)S6 and the modules are Engine 5...

It seems a bug. What would cause this?

this is a relatively new msg for E5 (via CSCsr99615, was around for E3 a
bit longer), which reports low buffer conditions in LC buffer pools. As
long as it doesn't pop up more often, it only reports a transient
condition and can be ignored. The check can be adapted/disabled via
"[no] hw-module slot <n> qm-sanity ..." command..
