I am almost a week into testing my jack-audio application with no crashes of jackd or my application. Bug abound (in my code), but that is the point of testing. Fixing as I go. I am using Ubuntu Studio control to run jackd... actually jackdbus, which brings me to my question:

How do I get control over jackdbus logging? I currently have an gigantic log file it is creating at ~/.log/jack/jackdbus.log from my testing.

It's huge because my application make extensive use of jacks inter-process audio routing as a radio station automation system. My application is endlessly forking new audio player processes that connect back to a core mixer via jack, play when needed, then disconnect when finished. So the above log file is crammed full of jack port connect and disconnect notices. How do I make it stop? There is no man page available for jackdbus, and "ps" indicates that it was simply run as "/usr/bin/jackdbus auto." With some further poking around I found that ubuntu-syudio-control is running something called autojack, which seems to run jackdbus, and autojack does have a man page, but not much help.

As a side note, the Patchage interconnection GUI does seem to cause jackd to crash after about two days of running. I have not troubleshot that any further, but I do know that without Patchage running, jackd has been running with my program for 5 days. There may be something worth investigating, but I haven't had time.
