Maybe capture a log (with netmon on wireshark) on the windows side to see what the trace shows. Presumably some odd networking issue with virtual box, but may be useful to see which command fails/timesout by looking at dmesg output on the client (running the test after enabling /proc/fs/cifs/cifsFYI setting it to 7 e.g.). At least with the server returning maxmpx of 50, it is less likely to be the bug with too many outstanding requests. -- Thanks, Steve -- To unsubscribe from this list: send the line "unsubscribe linux-cifs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
