We haven't had a chance to update to 1.9.8 yet, so we're still running
1.9.6 (Linux) in production, and just had 2 segfaults happen a little
over an hour apart. When I look at the core dumps from them, the stack
trace is the same. I'm not sure if this is an issue already fixed, so
providing just in case.
There was one oddity going on at the time these segfaults occurred. We
had maxed out the Linux kernel's conntrack table. So haproxy would have
been experiencing timeouts when attempting new connections, with health
checks failing all over the place.
