    I have a f24 workstation (nfs client). It is updated regularly.
    The server is f19, so no updates there.

    A problem started in the last few weeks. When I examine a file on the 
server it
    looks OK. The file is updated every minute (collecting some stats) and 
'tail' shows
    the added lines as they arrive.

    Examining the same file from the workstation is initially OK, but then, as 
the file
    grows, I get binary zeroes at the end of the file. The same with tail, 
less, vi, etc.
    The amount of zeroes seems to be the size of the extra data appended to the 
file.
    'ls' shows the actual (full) size of the file. It looks like the utilities 
see the
    correct size but bad data is delivered at the tail.

    After a few minutes the full data is showing but then, as the file grows, 
again I get
    zeroes for a few minutes.

    Where do I look next?

    TIA

What does your export config look like?

server (.7)
===========

$ cat /etc/exports
/data              192.168.3.0/24(rw,async)

$ sudo exportfs -v
/data           
192.168.3.0/24(rw,async,wdelay,root_squash,no_subtree_check,sec=sys,rw,secure,root_squash,no_all_squash)

client (.4)
===========

$cat /etc/fstab
files:/data     /data-e7       nfs    soft   0   0

$ mount
=======
files:/data on /data-e7 type nfs4 
(rw,relatime,vers=4.1,rsize=1048576,wsize=1048576,namlen=255,soft,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=192.168.3.4,local_lock=none,addr=192.168.3.7)
