I'm using kernel 2.6.35.
It could well be that I'm mistaken and that the runaway happens when the process first starts and not after some time.
I'm going to put some monitoring on to check if the netlink socket exists when the process is started or disapears after some time.
I'll report back in a few days.
Thanks for all of your help.
