Paul, none of what you suggested crashed ardour here. All tests (7 
minute session, 1 mono track, up- and downsampling, rt and non-rt) 
were with jackstart -p 2048 though. Read Jan's message and tried to 
reproduce David's crash. I get the crash too, in realtime-mode it's 
a freaking hard crash, in non-realtime ardour goes and jackd is 
alive. See below for the backtrace.

Happens *only* with jackd @ -p 128 -n 2 and upsampling 44.1 -> 48, 
not with -p <> 128 and not with 44.1 -> 44.1

Wolfgang

jack's messages has
subgraph starting at ardour timed out (subgraph_wait_fd=11, status = 0, state = Triggered)
process cycle within freewheel failed
when it happens.

jackd 0.99.30 (jackstart -p 512 -d alsa -r 44100 -p 128 -n 2)
