Hi,
I'm experiencing a seqfault when running Petri-Foo:
[~]$ petri-foo
lash_open_socket: could not connect to host 'localhost', service '14541'
lash_comm_connect_to_server: could not create server connection
JACK error: This system has no accessible HPET device (Device or resource busy)
Connected to JACK server with client name 'LASH_Server'
Opened ALSA sequencer with client ID 130
Listening for connections
Created project project-1 in directory /home/josh/audio-projects/project-1
Added client 87edbf96-21e0-4085-9c2b-3c512400aea6 of class petri-foo
to project project-1
Client 87edbf96-21e0-4085-9c2b-3c512400aea6 set its name to 'petri-foo'

[~]$ Client petri-foo removed from project project-1
Project project-1 removed
there are two things here that aren't clear to me:
1. I configured the software with --disable-lash, yet it's trying to
start lash anyway...
Ok thanks, I'll look into it. That's a problem inherited from Specimen ;-)
2. members of the audio group have permissions to use
(is that the
right word?) the HPET timer, but it's saying it's busy, maybe because
jack is already running?
This might be a problem with how you've configured JACK. Some questions to ask:
1) Does your motherboard have a HPET device?
2) Is the Kernel/Alsa configured for the HPET device (if it exists) to work?
This might help:

Or you could remove the --clocksource OR -c [ c(ycle) | h(pet) |
s(ystem) ] option from the Jackd command line.
I don't know where it's seg-faulting or why. If you have the time and
inclination you could do the following:
rebuild:
1) cd Petri-Foo
2) make clean
3) ./configure --enable-debug
4) make
enable core dumps:
5) ulimit -c unlimited
run:
6) src/petri-foo
hopefully it will have segfaulted again in the same way.
load petri-foo and the core dump into Gnu Debugger:
7) gdb src/petri-foo core
get backtrace:
8) thread apply all bt
copy and post to petri-foo-devel. subscribe here:

Thanks.
