Jack2 after Ardour does a session export requires a restart

[Ng Oon-Ee]

Hi all,

When I export my session from Ardour, qjackctl's "connections" window
shows all connections as broken off, and no other apps from that point
on can connect to jack until I do a jack_control exit and jack_control
start.

The relevant errors are, I think:-

Sat Nov  7 18:17:07 2009: ERROR: Cannot set scheduling priority
for RT thread res = 22 err = No such file or directory
Sat Nov  7 18:17:07 2009: ERROR: Cannot start thread

Sat Nov  7 18:17:13 2009: ERROR:
JackProcessSync::LockedTimedWait error usec = 53320 err = Connection
timed out
Sat Nov  7 18:17:13 2009: ERROR:
JackProcessSync::LockedTimedWait error usec = 10664 err = Connection
timed out

Attaching the full (minimal to produce the problem) jackdbus.log.

This seems exactly the same issue Andreas reported some days ago.  It  
seems something concerning thread priority setting was not correct or  
al least was changed in recent kernels. Fix (should be) in JACK2 SVN  
rev 3717.

Can you test and report?

Thanks

Stéphane

Ah, didn't realize my distro already had a script for jack2-svn. Am
happy to report that this is fixed as you mentioned. Well, I'm on rev
3718, but still. Problem mentioned in first email is non-reproducible
after multiple tries.
