Hi Will :)

maybe valgrind --tool=memcheck rosegarden (and other applications) might
be a help to detect what's going wrong, I have to read about Valgrind's
functions. It would be good to have a protocol of complete audio sessions.

Something about Memtest:

Memtest can run about 30 hours and more without any error. Very seldom
it gets errors running after reboot, within the first seconds, but after
that first errors, it runs around 30 hours without getting more errors.
I can't do such long tests very often.

The setup I try to make music with at the moment uses:

QJackCtl 0.2.22, jackd 0.103.0 (not jackdmp)
QSampler 0.2.1 (only 1 .gig)
JackRack 1.4.5 (only GVerb)
JackEQ 0.4.1 (not the EQ, just the mixer)
JAMin (often in bypass mode)
all those applications are default 64 Studio installs.

Rosegarden 1.7.1 (only MIDI tracks, without LADSPAs, but with several
Fluidsynth-DSSIs)
is from the backports.

jack-snapshot
is compiled, but without manipulating any dependencies.

Is one of those applications known as unstable?

I'm running GNOME Terminal 2.14.2 too, sometimes also htop 0.6.3, all
are default, resp. Etch.

Jitter is existing, but not hearable, the problem are to many crashes,
not if Rosegarden plays anything, only if I play or record something,
than Rosegarden or QJackCtl will crash, I don't know which application's
fault this is and also QSampler can crash.

Cheers,
Ralf
