When I run jackd from the 64studio version of qjackctl, jackd crashes
either straight after starting, or within 5-10 minutes, with the following
error in the log:

{{{
09:07:45.867 Audio connection change.
09:19:12.707 MIDI connection graph change.
09:19:12.708 Shutdown notification.
09:19:12.709 Client deactivated.
09:19:12.710 JACK was stopped successfully.
zombified - calling shutdown handler
cannot send request type 7 to server
cannot read result for request type 7 from server (Broken pipe)
cannot send request type 7 to server
cannot read result for request type 7 from server (Broken pipe)
}}}

This does not happen when I run jackd standalone, or using the debian
stable version of qjackctl. It does happen even when qjackctl is the only
jack application running. Also note that the crash happens straight after
a midi connection graph change, which makes me think that it is a bug in
the midi subsystem of qjackctl (64studio version). I am using an M-Audio
firewire solo card, with the freebob / ffdao jack driver.

jackd is started with the following parameters:

jackd -v -R -P89 -t2000 -dfreebob -dhw:0 -r48000 -p256 -n3 -i0 -o0

This problem has also been reported in the following forum thread:

Comment:

The only change in qjackctl version 0.2.22-2 compared to 0.2.22-1 was to
do with window positioning, it's hard to image it could cause this
problem. However this is an old version of the package, almost 18 months
old, so we'll have to test against a current version in a beta of 64
Studio 3.0.
