Hi,
I don't know if this is a bug or it's it's a misconfig or something
else.

What I have is:
    server = 1.6.4.1+vanilla 2.6.18.8   (mgs+2*ost+mdt all on a single
server)
   clients = cvs.20080116+2.6.23.12

I mounted the server from several clients and several hours later
noticed the top display below.  dmesg show some lustre errors (also
below).Can someone comment on what could be going on?

Thanks,
Ron
