IPv6 DHT banning everyone

[Spacey]

Win10 Pro 64 bit.  System info:

Java 1.8.0_51 (64 bit)
 Oracle Corporation
SWT v4508, win32
Windows 8.1 v6.3, amd64
V5.7.2.0/4 az3

I suspect there is a bug/issue with IPv6 DHT banning all or most nodes.  I always see a very high number of banned nodes.  Every banned address I see is IPv6.  This has been going on for months (including previous Vuze versions) so it isn't a new or temporary thing.

If I'm reading the statistics page correctly, there are 10 live IPv6 contacts ... and 48 banned addresses.  It seems likely that something bad is going on with it being too quick to ban.  Maybe because there are few IPv6 nodes, an individual pair of nodes tends to talk to each other more often, triggering the flood protection?

Example:

[18.05.2016 17:18:17]    [DHT: Sender stored excessive entries at this node (global flood)]     2601:681:4000:3e36:540f:8d93:b3d7:e260 has been banned
[21.05.2016 02:38:29]    [DHT: Sender stored excessive entries at this node (global flood)]     2a00:a580:10b2:e000:6dec:470d:dc27:30c5 has been banned
[16.05.2016 17:44:18]    [DHT: Sender stored excessive entries at this node (global flood)]     2a01:240:fe00:8277:0:0:0:100 has been banned

That could be why lately my upload speed is so irregular and usually low... I don't know, it's weird.

It is possible that, as you say, the small size of the IPv6 DHT is causing this issue - unfortunately I don't have a means to test this out. I'll take a guess at a fix - please tell me if things have improved in the next beta.

I can't see how this would affect your upload/download rates though
