I just grepped my source tree and there's no occurence of "jack_create_thread", "switching current thread to rt", or "inheritance" whatsoever. There is a "jack_client_create_thread" however. So maybe the problem is a mismatch between client and server JACK versions? Maybe your upgrade pulled in an older version of JACK. Lee
