Yeah, I discovered some vicious Gabble bugs when using hyperactivity.
One of my fix [1] wasn't merged yet. I will ask to Daf to review it.

Sorry about that, I forgot to push my patch after the API change. Please
update your hyperactivity with [2].

I also observed issues when running too much connections on the same
Gabble instance (IIRC around 250 connections as you). I'll continue to
test and try to fix more of them.

For now, you can run multi instances of Gabble and hyperactivity.
Hyperactivity doesn't support multi instances yet, so you'll have to
make a full copy of it for each instance (don't forget to erase your
accounts directory to create new ones). I should fix that too.
