CIFS VFS: Server xxx has not responded in 120 seconds

I am having a problem with a Windows mount that becomes unavailable and hang any process accessing it.

Doing a dmesg gives this:

[ 1566.033468] CIFS VFS: Server xxx.xxx.xxx.xx has not responded in 120 seconds. Reconnecting...

But nothing happens.

I'm running Ubuntu 13.10 in Virtual Box 4.3.4 that runs in Windows.

When I reboot, everything works fine for a bit. When I stop accessing the mount point for 15-30 minutes, I get the error.

I found the following information: but it did not help.

Also found bugs in samba: & it links to bug #9422 also.

Not sure if it is related.

Any help appreciated.

Thanks, Marc

I find that this happens when underlying storage is very slow. I have VM which has problems with the SAN timing out and i see these messages on regular bases. What is you setup VM or physical servers?
