Hello. I know that NFS is undergoing continuing changes and updates and
don't know if
the oops I'm getting is already on someones todo list. I run a database
archive then
push to a nas box via nfs. It looks like most of the data arrives,
but then the file transfer fails to end.
It initially ends like this:
nfs: server 192.168.20.114 not responding, still trying
And then becomes this:
