[arm-allstar] Strange Errors, can't reconnect nodes on same Pi

[M Lech]

What might explain my server going berserk with these messages:

It just keeps on scrolling, stuck in a seemingly endless loop. This is
after running for 70+ days. I typically connect two nodes together on the
same Pi. One is a Public Gateway, the other (777) is an "internal hub" for
RTCMs. There are no USB adapters, only the RTCM/Voter channel driver and
the pseudo "dummy" channel driver for the public node.

When this happens, the two cannot connect to each other. Connections to
other nodes will establish, but traffic only flows inbound from external
nodes. Not outbound from 777 to other nodes. Restarting Asterisk clears the
error, but doesn't solve the problem. Is there a settings problem,
corrupted memory perhaps, or coding bug?
