Lukas, 1.6.3 didn't have any crashes. These crashes are sporadic and are not happening under the load, there is very little traffic as we are not running production yet. The proxy starts fine and can run for hours with the crash. Where would the core be generated? I set it up running as user haproxy would I have to adjust limits for that user?
