kern/166071: High CPU Utilization on HylaFAX processes

[Ryan Noll]

The PR is available at: http://www.freebsd.org/cgi/query-pr.cgi?pr=166071.

Below is some more information about this particular bug. I thought this
could be a kernel bug, but maybe it could be a bug in the program that the
9.0-RELEASE kernel exposed.

If the faxq and hfaxd processes are started (via their startup script) and
then faxgetty is started all appears fine.

However, while sending a fax the faxgetty process is again at 100%. The
truss output for faxgetty is not included because it is the same as stated
earlier. After the fax has completed, faxgetty remains at 100%.

Should this still be considered a kernel bug or should I try contacting the
HylaFAX maintainers?

Note that the configuration is run in a jail with a USB (cuaU0, MultiTech
MultiModem MT9234ZBA-USB-CDC) and serial modem (cuau0, MultiTech MultiModem
MT9234ZBA-NAM). This configuration did work under 8.2-RELEASE-p6. Also,
this message is shown during the initial setup probe: stty: stdout appears
redirected, but stdin is the control descriptor.

Thank you for your time.

v/r,
Ryan
