[F10-nsp] Packet drops on S50N using VRRP

[Adam Waite]

We've run into the "LACP restarts during a write mem" bug too, and it
prevented us from upgrading beyond FTOS 7.7.1.1 for a long time.

I can report that this particular bug has been fixed in the latest versions,
and we are now running on 8.3.1.x, with no real problems after several
weeks.

Sameer, I'd suggest upgrading to the latest code, and see if the problem
still exists.
