This is with your fifth patch on top of the previous four patches: http://iucha.net/nfs/21-rc7-nfs3/big-copy Again, it has memory, stack traces and rpc_debug. The iostat 5 output: http://iucha.net/nfs/21-rc7-nfs3/iostat The netstat outputs are stable (not changed in 5 minutes): http://iucha.net/nfs/21-rc7-nfs3/netstat-server : tcp 1 0 hermes.iucha.org:nfs zeus.iucha.org:799 CLOSE_WAIT tcp 0 0 hermes.iucha.org:nfs zeus.iucha.org:976 ESTABLISHED http://iucha.net/nfs/21-rc7-nfs3/netstat-client Active Internet connections (w/o servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 zeus.iucha.org:976 hermes.iucha.org:nfs ESTABLISHED tcp 0 0 zeus.iucha.org:ssh hermes.iucha.org:56880 ESTABLISHED tcp 0 0 zeus.iucha.org:ssh hermes.iucha.org:45176 ESTABLISHED Could the port in CLOSE_WAIT state be the culprit? (FWIW the server has been up for 38 days and subjected to this nfs test quite a bit without showing any stress).
