Mac OS X 10.6.8 Transmission Version 2.52 (13304)
Currently have 1 active torrent from a private tracker.
Tracker currently has 7 seeders with 100%. Transmission initially connects to all of these with download rate +1MB/sec. After a few minutes six of the seeders vanish with only one remaining download rate drops to less than 100KB/sec. The 100% seeders are still in the swarm, Transmission drops them and never reconnects.
Preferences set-PEX, DHT, use local peer discovery, prefer encrypted peers is on. Max connections set at 2048, Max connections for new transfers 96.
uTorrent connects to all seven 100% seeders and remains connected and thus retain 1MB+/sec with no issues.
What else can I provide to the dev team to help them investigate this? I've seen this problem on/off with Transmission for many years and it still isn't resolved. uTorrent has no problems connecting to all seeders in the swarm.
