Yes, it appears that I do.  On the basis of this I've just noticed that
kill -CONT <pid> brings it back to life so perhaps this isn't as serious
as I had previously thought.

I'm running a different kernel now though so can't say for sure,
previously I know I had to reboot the node to clear it however this was
a function of the way that I was starting processes.  Curiously this
only seemed to affect Redhat kernels so I switched to using vanilla
kernels which combined with running a modified gdb means I haven't
observed this happen for a while.
