[App_rpt-users] Dial Watchdog Function

hi steve

the main issue steve is not the fact that
service asterisk restart does not work.

but the main issue is that if asterisk crashes for any reason
it will not restart itself. because of this i also can not use
cop,1 cop command which is asterisk restart.

cop,1 will cause asterisk to exit for restart but asterisk will
not restart via a watchdog script.

safe_asterisk used to do this very nicely but it has been eliminated.
and you only use the asterisk service script under systemd.

yes the version of the asterisk service script i have here from the
dial build from about 4 to 5 weeks ago the
service asterisk restart does not work.

it force's me to use service asterisk stop to remove the
asterisk.ctl file from the /var/run and the
the service asterisk start will then work allowing asterisk
to be restarted proprely.

I also have a node setup for remote base mode using an
ic-706mkiig and sometimes that will cause a crash with it.
when asterisk is accessed via an allmon2 dashboard.

I have had to take the remote base node off of the
allmon2 page to stop this crashing.

it will do it every time too.
that is something with the old remote base code
with in app_rpt.c too which has never been fixed.

this is why the asterisk auto restart on crash would be very nice

where can i find a new or updated asterisk service script.

can i get it from the rpi2 dial image and put in the
dial x86 build with out having to re-install
dial x86 image?

otherwise for the most part asterisk under dial has been
fairly stable. but i can make it crash under certain conditions
which i try to avoid. like using allmon2 to access
the remote base node via the asterisk manager
interface.
