Maybe some 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?
