[j-nsp] Immediate aging in EX-3200

Hi,

There is no link flap. At the same interface I have about 1000 other
VLANS and about 5000 other MAC's and they don't flap. The problem
affects only a one or a few MAC's at a time.
I should double check for a bridging loop but I don't believe there is one.

I use Junos 10.1R1

Regards: Emil
