I don't have a solution for your problem, but a way to avoid it, 
together with getting the service you require.

For sharing partitions, I use the automounter (autofs). I uncomment the 
"/net    -hosts" in /etc/autofs/auto.master.
Assume that you also do that and have the line "192.168.2.4 linux-5" in 
/etc/hosts.
Then to access a remote file on linux-5, you just have to do something like:
"ls /net/linux-5/home/marc/Documents/Marc/Famille/Photos" to get it 
mounted and accessible.
In fact, any access to a file or directory named like this causes the 
mount to occur.
You can also have links to such names to make your access simpler.
For example (avoid the use /mnt for such things, it's confusing with 
system mounts):
ln -s /net/linux-5/home/marc/Documents/Marc/Famille/Photos /Shares/Photos
Accessing /Shares/Photos causes the remote mount to occur.

The advantage of using the automounter is mainly that mounts are only 
done when required, and disappear when no longer in use. This highly 
reduces the risk of having stale NFS handles. As it is used by many 
people, it also works ;-)

Automounting work also with local partitions, I use it also for the 
local Windows ones to avoid to have them mounted when they are not used, 
while having a transparent mount when I need to access them.

Hope this helps.
