Subject Re: Regions offlined..
Date Sat, 21 Aug 2010 00:01:16 GMT
Changes.txt says that this particular issue was fixed..

Could there be another reason why I see this problem?

I know that restarting might resolve this issue but I just wanted to check with you guys the
potential cause for the problem..

Thank you
Vidhya
