[Lustre-discuss] no handle for file close

[Nirmal Seenu]

I am getting quite a few errors similar to the following error on the 
MDS server which is running the latest 1.6.7.1 patched kernel. The 
clients are running 1.6.7 patchless client on 2.6.18-128.1.6.el5 kernel 
and this cluster has 130 nodes/Lustre clients and uses GigE network.

I don't see the same errors on another cluster/Lustre installation with 
2000 Lustre clients which uses Infiniband network.

I looked at the following bugs 19328, 18946, 18192 and 19085 but I am 
not sure if any of those bugs apply to this error. I would appreciate it 
someone could help me understand these errors and possibly suggest the 
solution.

TIA
