CM-1 Modules crashing?

This problem began happening a few days ago..   at first I thought it was a glitch but it repeated the error again this morning.    This is what I am seeing in the remote log.  After this happens..  all of the NION's I have using cobra net mute.

Has anyone seen this before?   Or know what it is doing?   I am not sure what to look for on this.

Thank you!
