Comment 20 for bug 579276

We use vmware ESXi, and we were crippled by this bug (we had to rebuild several systems back to karmic because they were so unusable). Somewhere in the past month a kernel upgrade seems to have resolved this issue for us. We could reproduce this problem easily:

Remote System:
cat /dev/zero | nc -w 4 -l -p 5000

Vmware lucid system:
nc othersystem 5000 > /path/on/nfs

That could reproduce the issue in a few seconds. Now that runs for 30+mins w/o any issues, and our "real world" scenario use case appears fixed too.
