[arm-allstar] Link Activity Timer Not Always Working

[David McGough]

Larry,

Did this problem start after changing to using a VPS-based hub node?

Are you using HamVoIP dual-registration?

a friend’s repeater node, and my dad’s simplex node connecting to my hub 
node.  On my repeater, my friend’s repeater, and my dad’s node, we use 
the link activity timer to disconnect all nodes and reconnect back to my 
hub node.  As I mentioned, this has been working for the most part.  
However, on my friend’s repeater and my dad’s node, it will occasionally 
disconnect from the hub, and won’t reconnect.  Hours will pass and it 
will not reconnect back to the hub.  Eventually, one of us will notice 
the link is down, and send the command to run the script, and it 
reconnects back to the hub.  Nothing has changed on either of the nodes, 
and it seems like this problem is occurring much more frequently within 
the past week.

node to a cloud server for several reasons, but was also trying to 
troubleshoot this problem.  Unfortunately, even once I moved the hub to 
the cloud, I found the problem with the two nodes remaining disconnected 
is still happening.  I am baffled by this problem because it doesn’t 
always happen.  I have not been able to consistently recreate the 
problem, so I have not been able to identify the cause.

Remember that I am not having this problem with my repeater, but the same 
lines are used in my dad’s and my friend’s rpt.conf files.
