Thanks for the info. Just curious, what HW specs (ncpus, RAM) is available on that system? I wonder if that affects timing somehow... > (And again, if you want to have a look yourself, I'd be > happy to give you access to the machine; still the same > testing OC VM.) Unfortunately, my *BSD debugging knowledge is far behind my Linux; so I'm not sure how much help it'd be... Some examples of things I miss on OpenBSD: * /proc/$PID/fdinfo/$FD_OF_EPOLL on Linux is immensely helpful for knowing what and how epoll is watching target FDs. I'm not sure if there's a way to introspect kqueue like that * Linux strace decodes more struct args info than kdump * ability to control pathname of core dumps ... probably a few other things, but been sick a few days and brain still foggy :<
