If the message authenticator is all zeros, then I can send a request from one freeradius server to another with out any problems. The problem is when I user Radiator with freeradius sending accounting messages to it, it complains about Authentication failure. So I assumed that Radiator does not like a blank MA. Hence I tried to produce one and add it to the accounting packet before sending it to Radiator. However it still fails.

The accounting packet is signed by the client therefore there cannot be two signatures created for the entire the packet. By the very nature of creating signature the second signature will alter the packet's contents invalidating the first signature. The Message-Authenticator can be only one of two things. Either it's calculated as a hash of the attributes or it's a random number (like the Access-Request authenticator). From your information I suspect it's the former. You might try using the traditional MA calculation for the MA on just the attributes with an empty (zeroed) MA present and back patch the MA. If this works please let me know. Or, if someone has accounting packets generated with proper MA's please send them to me and I'll try some standard hashes. The MA is traditionally created as an MD5-HMAC of the shared secret and the entire packet's contents with an empty (16 byte) Message-Authenticator. For an accounting packet MA use just the attribute block instead of the entire packet try just the attributes with the empty MA.

Doing the upgrade slowly is less work than doing it quickly, and then having your RADIUS server down because you missed something.

Yes. If all of the threads are blocked forever, waiting for the DB to return data, then the queue of requests grows without bounds. At some point, the server says "I'm not making progress, and I can't recover from this", and kills itself. Since the server is *already* effectively dead at that point, it makes no difference to your network. The solution is to fix the database so that it doesn't kill the server.
