On my computer, I noticed that jack does have a tendency to lockup after a while when jackdbus is running. I had the feeling that it might be something to do with latency, as I found it is impossible to start jack at very low latencies with jackdbus running. I was using 128 samples which seemed to be OK, but at that latency, the lockups occurred after some time. I tried increasing latency to 256 samples/44.1k. Following this, it seems to operate fine (at least I have had no more dropouts), but it is all a bit fiddly to get it to work properly, and I would probably disable pulse if I wanted to do serious recording etc without the mixing capabilities that jackdbus adds..
