Hi Guys I thought I should report the following as a possible Bug.
I dialed up the following Echolink node last night to help out with Jota in the area and left it running over night.
*33 138203 (JOTA-E).
When I went to check it again today at about 2PM the Transmitter was locked on solid and there was no Audio.
I checked the asterisk box to see that Asterisk has dropped out with an error and the DMK dongle had left the Transceiver locked on TX. 
Both the Green and the Red lights of the DMK Dongle were on Solid (Not Flashing)…
Here is what was on the screen

I think this is the only relevent bit. But below is a longer section of the console msg’s just in case.
Hope this is of some help. .
