As everyone will recall the exchange has had problems with the main switch flooding unicast traffic a couple times in the last few years.  Juniper believes we’re encountering a known bug that has been fixed in later software releases.   Here’s the bug description for people with Juniper support ids, as we’d suspected it deals with L2 database MAC learning/maintaining:

The upgrade will require a short interruption in exchange traffic.   We’re currently planning on performing the upgrade next week on Wednesday morning - July 29th between 5am and 7am, that should be the low point in our daily traffic volume.

Can someone forward this to the Announce list?

Cheers,
