The version running when the kernel died didn't set permanent: the output shows no sign of a helper associating with my userspace expectations. >>> Please, send me the code so I can reproduce the problem here. For what its worth, my prototype is here: https://github.com/sam-github/libnet/blob/master/lua/echoconntracker https://github.com/sam-github/libnet/blob/master/lua/echoserver https://github.com/sam-github/libnet/blob/master/lua/echoclient You have to build the whole libnet (and yes, this code has nothing to do with libnet, and I'll rip it out somewhere else RSN). >> Its not reproduceable, it seems more like a race condition leaving >> pointers in an undefined state.

When this happened, I was running the prototype conntracker, and several instances of conntrack -E (for each table). I typed a conntrack -L command, and the kernel died after I hit ENTER. Could be unrelated to that, but seems suspiciously coincidental that the backtrace shown reflects something I did (it looks related to printing conntracks). Still, you would know better than me what the kernel does when things go wrong.
