SIGUSR2 is sent to apps by an -rt kernel if they requested user enabled
latency tracing. You probably have compiled jackd with
--enable-preemption-check which turns on user enabled latency tracing
around each app's proces callback().

If you don't fully understand what that does, i'd recommend you to turn
it off. It will probably fix your problem. So rebuild jack without that
