Comment 5 for bug 236389

I'm sorry Dimitrios, I have switched to a different solution and the machine has been in production for some time now so I don't have it handy to test a more recent Ubuntu.

It really is a deadly serious bug though which prevents using Ubuntu on servers with huge amounts of RAM. If I buy any new hardware in the near future I will try ubuntu again, revisit the bug and post my findings. Thanks for taking an interest.
