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

[Andy Whitcroft]

We have had some success preventing this behaviour by adjusting a kernel
tunable.  If those who are able to reproduce this could try increasing
the sysctl 'vm.min_free_kbytes' and see how that affects their tests.
We have been running with this value approximatly 10x its default value
for our testing though this is likely an excessive bump.

    # sysctl vm.min_free_kbytes
    vm.min_free_kbytes = 8080
    # sysctl vm.min_free_kbytes=80800
    #

Please report any testing back here on this bug.  Thanks.
