Stability with CIFS transfers

[lurium]

My readynas pro gets into some kind of unstability when i transfer files to it using windows and cifs.

Samba stops responding but i can access the WEB GUI. But when i go to "health" GUI also hangs.

Only thing that works is to close firefox, go back into gui and do a reboot.

Then if im stupid enough to try do another "write" it all happens again.

Nothing in logs...

Could be a flaky disk. I would definitely test the disks using vendor tools to eliminate them as the culprit - http://home.bott.ca/webserver/?p=388

Strangely it works flawless if i transfer the same amount of data using ftp.

But cifs... no way!

In my /var/log/samba/log.smbd i get some disturbing errors...

[2011/09/20 15:04:56.119884, 0] smbd/process.c:79(srv_send_smb)
Error writing 75 bytes to client. -1. (Transport endpoint is not connected)

Might have found the reason... my windows 7 pc had jumbo frames disabled on its NIC.
After enabling jumbo frames and transfering files using cifs it doesnt crash the readynas (samba).

So basically 1 client with jumbo frames disabled can crash samba... ehhh????

(edit: added "smb ports=139" to /etc/samba/smb.conf ) .. no crash yet with jumbo frames turned of on win7 client.
