Apologies for the confusion;  the patch quoted is essentially the first patch 
you provided me, with my changes to make it work in 3.4.10 *plus* the deletion 
of the change to nf_conntrack_ecache.h where your patch deleted the 
nf_ct_is_dying() check (i.e I have this check left in) - with this 
modification, I find that conntrackd is well-behaved and I have thus far not 
successfully caused a kernel panic.

Having tested your latest patch, I can also confirm that it also does not 
crash, including at exhaustion of the conntrack table.

In terms of overall stability, I would presume your latest patch is superior 
to the previous (i.e. what I attached most recently) ?

Kind Regards,
Oliver
