On my currently running system there is only one jackdbus task running. I see the parallel jackdbus tasks in another crash dump I have. I do have problems with jackdbus hanging from time to time and I kill the current task - the service restarts a new jackdbus task. Might be that the task that has been "killed" but is really still alive when the next task starts? -- You are receiving this mail because: You are on the CC list for the bug.
