Yet another registration problem

We have a large linked network of 900 MHz repeaters. Our main server has 5 HUBs and a handfull of RTCMs defined in the same rpt.conf. This has been stable for a number of years. Today only 2 of the 5 HUBs are registered. I’ve tried shutting asterisk down for 5 minutes and restarting. It’s odd that the same 3 HUB nodes don’t register. The two HUB nodes that DO register are: 41170 and 42610. The three HUB nodes NOT registering are: 27714, 42947 and 49729.

I’ve submitted a help ticket.

Thanks,
Tom / K5TRA
