[Ardour-Users] Adding tracks or busses disconnects Ardour from JACK

[Q]

Hi Harry

Thanks for this.

I checked the Timeout, it was set to 2000. I expect it's probably 
inherited this from my previous set-up (I keep the same /home partition 
when I do a fresh install). I increased it to 5000 and it didn't make 
any difference.

When it disconnects, it's the very moment that I click to make a change 
in Ardour that the connections to Jack go. There doesn't seem to be any 
delay, like you sometimes get with misbehaving software being slow and 
then Jack kicks it out after the timeout period.

Thanks again,

Q
