[Samba] smb_trans2_request: result=-104, setting invalid

[David Leuser II]

I'm having problems with smb connections either timing out or becoming
corrupted after about 5 minutes of inactivity???  We mount all our user
homedirs (smb shares) through pam_mount at login.  The workaround is to
logout and login again.

/var/log/messages has a line that looks related: kernel:
smb_trans2_request: result=-104, setting invalid

Please help!
