Lustre discuss - Sep 2009 - Error: ldlm_resource_add()

hi,
I used lustre 1.8 on CentOS 5.0.
When I was uploading a file on client, I had a problem with ldlm_resource.c.
The follwoing are logs on OST3:

And, I had not uploaded file on client.
Can you tell me, what''s that? and how to fix it?
Sorry, if the sentence structure is wrong. :)

Thanks,

Dear list,

when I mount the Lustre filesystem from a 1.8.1 client (which
had been a 1.6.7 client before) I get the following message on 
all OSTs:
LustreError: 3877:0:(socklnd_cb.c:2228:ksocknal_recv_hello()) Unknown protocol
version (2.x expected) from 192.168.2.43

There seems to be no problem using Lustre from this client, so
is this just a warning, which can be ignored?

Bye, Ralf
