Not sure if this makes a difference, but can you send the complete
messages (incl. the tracebacks) and a "show ver" so we can decode the
message?
Finding the trigger is the key to diagnose this further (and looking at
the cef events will help). CEF LC IPC Background is responsible to
process all CEF IPC messages from the RSP, so this could be almost
anything.
