[App_rpt-users] RB stability, was: Dial Watchdog Function

Hi Ken,

Interesting that having allmon2 probe the RB stats causes a Asterisk
crash...Back in yesteryear I tried to run a 706mkiig RB using the built-in
code and never had good results--YES, it did work. But, Asterisk wasn't
stable very long, frequently crashing several times a day, depending on
use.  Various serial communications issues with the radio would
-sporadically- "knock it for a loop" too. I concluded that their was
probably memory getting clobbered somewhere.

If I disabled the RB command support, the Asterisk stability
skyrocketed--uptimes now measured in weeks, months or longer. As an
example, here are the stats from one of my RB systems now:

TX time today....................................: 01:12:27.95
TX time since system initialization..............: 87:37:42.861
Uptime...........................................: 1336:34:22

It has been up 55 days without any issues....And, as you can see, it gets
used--But, I now use hamlib for all RB commands.


73, David KB4FXC
