[Bug 561210] Re: Writing big files to NFS target causes system lock up

[Alex]

@Timo Harmonen

I reverted my sysctl settings and indeed it stalled again when using
your cp-script. After reenabling the sysctl settings and copying about
40GB I still could not get it to stall. So it seems that the sysctl
settings really fixed the problem for me. At least with Lucid kernel
2.6.32-24.42.

For comparison here are my NFS settings. All clients are connected via
GB-LAN:

Server: rw,sync,no_subtree_check,no_root_squash
Client: hard,fg,rsize=16384,wsize=16384,acl

I hope you'll find a solution for your problem, too. Good Luck.
