Can you please post the contents of "cat /proc/mounts"? Of course.

Please leave the timeout at 60seconds (timeo=600) when using a TCP connection. TCP provides reliability guarantees that make resends unnecessary, except in the event of a disconnection. Thanks man. I have been focusing so mush on the server side of things that I completely forgot to have a look at the client settings. Thanks a lot. No problem. Closing this bug then... |
