Large NFS file transfers freeze up my system
 
Just wanted to make sure I didn't have some configuration error or something. When transferring large files like more than a couple GB, my desktop becomes completely unresponsive. I can SSH to the system and run commands and top shows CPU usage next to 0. But I can't do anything in the GUI. Also, some programs act as if they've lost internet access. This happens both on my Fedora 16 computer running KDE and my Linux Mint computer running Gnome.

I think I'm having the same issue.

I recently switched to authenticating user accounts via LDAP and Kerberos, and mounting my home directory using NFSv4 via Autofs.

This all seems to work reasonably well, except for the fact that occasionally my system will just freeze the GUI, and I can't click on anything. It seems to happen most when I open the Evolution email client.

I can get around the problem by switching to a text console, logging in, and doing sudo service lightdm restart, but it takes a very long time to restart, and of course I have to re-log in and loose all my unsaved work.

Does anyone know what might be causing this?

Any help would be very much appreciated - it's driving me mad!

Config files
 
My autofs mount config:

Code:
lloydsmart@tank:~$ cat /etc/auto.home
*        -fstype=nfs4,sec=krb5p        oracle.lloydsmart.com:/home/&
/etc/exports on the server:
Code:
lloydsmart@oracle:~$ cat /etc/exports
# /etc/exports: the access control list for filesystems which may be exported
#                to NFS clients.  See exports(5).

/srv/nfs4        fdd8:12ad:ec46:1::/64(rw,sync,fsid=0,crossmnt,no_subtree_check,no_root_squash,sec=krb5p)
/srv/nfs4/home        fdd8:12ad:ec46:1::/64(rw,sync,no_subtree_check,no_root_squash,sec=krb5p)
Are there any other configs I should be looking at?
