sounds similar to my issue with mksnap_ffs locking up in "D" state,
except that mksnap also locks the whole file system while it works,
so if it freezes, so does the full FS.

I'm running 6.2-PRE from 9/23.

yeah, that's true, ps ax shows the "cp" process staing in D state. by
the way, the server is unavailable now, execpting ping. the whole
system is out.

the server is rebooted.

someone recommand me to use smbfs instead of nfs ( 5.4@smp )...

Or if you actually care about the problem then provide some useful
debugging information that will allow someone to work on fixing it :-)

See a previous reply to Vivek where I explained what is needed to help
debug this kind of problem.
