[App_rpt-users] Unable to connect to some nodes ?

[Mike Hugo]

I'm unable to connect to some nodes and most likely am doing something
silly.  Node has been running for ages. It is running limely linux. It
appears to properly registers on the stats page.  I can connect to some
nodes just fine other nodes I get this error:

  [Mar  5 23:42:07] NOTICE[1240]: chan_iax2.c:4071 __auto_congest:
Auto-congesting call due to slow response

To other nodes I get the error:
  [Mar  5 23:53:56] WARNING[1236]: chan_iax2.c:9438 socket_process: I
don't know how to authenticate radio to xxx.xxx.xxx.xxx   


I haven't changed anything since I migrated the node to the new system
months ago.  Actually today I tried to upgrade the software in an
attempt to fix it.  The troubleshooting steps on
http://ohnosec.org/drupal/node/65 all test fine.

Hints?


thanks
