The only way that is likely to fix the problem is if the unit somehow can 
be made to use longest prefix routing and bypass the ipfdb totally.

Someone at Extreme hinted that this might be possible with the hardware 
but I never got around checking if they implemented it in any software. 
Does anyone know?

If not, the basic rule is that you cannot use the 24e3, 200 and 300 and 
400 series for "internet routing", as their ipfdb is too small. If you 
have more than 1000-2000 concurrent "flows" (ie destination IPs) going on, 
it's going to behave as the original poster described.
