[arm-allstar] RPI with 3 FOBs

Thu Sep 13 11:51:02 EDT 2018

Roger,

   Just to expand on that a bit. What I would do is open two ssh sessions
to the effected server. One monitoring the Asterisk client and the other
the journal  -  journal -f  -   It is possible there is a USB error of some
kind that might be logging messages at a very fast rate to either the
journal or the /var/log/asterisk/messages file. The other possibility is
the /var/log/httpd/access_log and error_log files.
