Bug#491116: jackd: Unreasonable xrun numbers

Package: jackd
Version: 0.109.2-3
Severity: normal

After starting jackd with realtime priority, as a non-root user (using the
/etc/security/limits.conf trick described in /usr/share/doc/jackd/README.Debian),
I get very unreasonable xrun numbers in the Messages log of qjackctl. E.g.:

**** alsa_pcm: xrun of at least 1216234611802.112 msecs

That would correspond to a delay of about 33 hours :-)

Best regards,
Torquil Sørensen

Is your issue solved by the recommendation to use 3 periods that you got
from the jack list?

Yes, I no longer get these xrun messages now.
