ON the way to the internet servers you connect to, there's supposedly some kind of modem connection (DSL, UMTS etc...), which limits your bandwidth. Such a bottleneck causes IP packet drops, evokes TCP/IP retransmits and/or TCP packets arriving in the wrong order thus stressing the TCP/IP stack. If you beat at such a bottle neck with multiple TCP/IP connection, even more packet drops are evoked.

All our observations lead to the vast assumption, that all the deadlocks reported in conjunction with bittorrent clients etc. may be related to the TCP/IP stack being under stress. There's a patch which ha been applied during the 2.6.25 release cycle by SuSE, which fixes a deadlock within the TCP/IP implementation, so I'd really like to gegt feedback, whether our assumption may be true.
