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

[Ancoron Luziferis]

Jeremy,

I disagree with the status change to "Fix Released" as it is not
"fixed". The problem still occurs. It didn't occur for my main
workstation here as I have raised the rsize/wsize to 32MB on the NFS
mounts here and I am just issuing one to two NFS "transactions" at a
time, so it didn't come up in the first place.

However, even if I raise the rsize/wsize I still can reproduce this
issue by throwing a bit more work in parallel for the NFS mounts. On a
"standard" NFS mount just a "cp" of a 400 MB file from the NFS mount to
the same is sufficient to raise this issue again. This doesn't occur
every time but around every second or third run at least.

I'll try to test the workload required for my 32MB mounts to get stuck
too. After that I'll be able to build a small script as a test case for
that.
