CAED should NOT be doing this! On 1 Apr 2006, at 19:49, Lee Revell wrote:

If you build JACK with the preemption check option and use an -rt kernel
with the debug options enabled you may be able to get a stack trace if
the app blocks in the process() callback, but it won't help to debug a
client that simply takes too long. On Sat, 2006-04-01 at 13:27 -0500, Eric Dantan

Soft mode is an OK workaround, but you should still try to get the
bug(s) in Rivendell fixed that are causing JACK to kick it out.
There are caed
bugs causing this! Please tell! Now it is possible for the disk (or network IO to
under run in which
case the audio
breaks up, but that does not impact the process callaback.
Eric, can we have a way to reproduce please, this needs sorting.
patch -p1 < erics_braindead_patch
There is nothing to worry about. The question just came to mind because
I had managed to screw caed up enough to get it kicked out, so it
occured to me that we might want to consider softmode just for
insurance. Again, as far as I know the distributed caed does not have a
realtimeness problem.
mea culpa.
