Frequent Namespace ID exceptions

Hi all,

I am getting frequent Namespace Id exceptions . I am running hadoop
0.20.0 on a cluster of 8 machines. Data nodes work properly for some
time and then they stop automatically logging an error of NameSpaceID
exception . Iam manually deleting namespace data , formatting name
node and restarting again . What might be the problem ?

Also hadoop dfsadmin -report isn;t showing any result . Kinda gng into
sme infinite loop .

Please help.

Thanks
