Hi Eddie, OK maybe 'hard lock' was the wrong term to use, the kernel does not hang, BUT I loose complete keyboard access (although my console mouse still work??? hehe ), CTRL-C doesnt work, caps lock or any of the led keys doesnt work etc. After window drops to 0, Socket never sends data ever again, even after window grows back to a full window a split second later. Enabling chatter messages in Socket I see that Socket never gets scheduled again after window 0, BUT I'm unsure if it's purely a matter of Socket not being scheduled or click itself having problems. The keyboard lockup seems to indicate something more though...
For my tests I just used a simple config (your config seems better for testing though): FromDevice(eth0) -> Queue -> Socket(TCP, 10.51.1.2, 11000) -> Discard; Any ideas?
