It triggered the bug reliably in > less than 10 secs. ;-) Tarnation!! Ran httperf! Didnt hit it! :(. What were your settings? I extracted an old debug patch to implement dropping of packets - have a sysctl that controls the rate at which I can drop IP packets, so can also generate any kind of packet loss..So thought I would bang away with netperf using sendfile()/TCP_CORK. Thought it was in that code path. Will be running tests tmrw and the rest of this week on 2.5.70 +- patch. Will see if I can provoke any further hangs, stalls, wackiness of any flavor... thanks, Nivedita - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
