Perhaps I have not been entirely clear in my email. But the application 
that generally uses rteth0 does not get hold of it either when it cannot 
be found in /proc/rtnet/devices.
It appears that the application did have hold of rteth0 but lost it. 
When checking /proc/rtnet/devices after the application no longer has 
access to it, it appears to be gone.

The application code has been operational for 7 months on a number of 
separate but identical machines and never displayed this behaviour 
before. Only one of the machines is now playing up with this.

Its a bit worrying if you tell me that once the output of 
/proc/rtnet/devices has been generated, there is no more updating done 
there.

In that case what I am describing would seem almost impossible?

Kind regards,

Roland Tollenaar.
