Transmission 2.33 fails to connect to UDP trackers

I have basically the same issue as anyone else. Transmission used to work, now it doesn't. CPU Usage is high (~100%), no DL or UL, lots of message in the Recv-Q, etc ... I've upgraded and downgraded Transmission but no result. I've even bought a new Router (Netgear WNDR3800) to see if that helped but it didn't.

This is my netsstat output:
---

I've tried different setting in the settings.json file but last time it worked I had the following setting:

One thing that I have noticed is that before I got problems I usually saw 2 transmission-da processes sharing the ~100% CPU Usage, now I only have one transmission-da process using all the CPU. It does not seem to matter how many concurrent peers I allow or the amount of active Torrents.

What I would like is to have some better way of getting logs from Transmission, does anybody have any idea on how to get this?

HELP!!! :)
