It's all latency, and there are lots of reasons for it.  Link  
saturation.  Open connection list size.  SYN floods (triggers alarms  
on some SMC Barricades).  Traffic load (Netgear FVS114 can crash under  
the load).

Try reducing the number of active torrents and/or concurrent  
connections as well as limiting down and up bandwidth.
