How do I turn off websocket debug messages to the console? (Running BeagleBone+Angstrom+Cloud9)

In Cloud9 IDE on the I am getting lots of debug messages like the following:

"debug - websocket writing 5:::{“name”:“state_changed…”

These, I believe, are written to the console by every time I send a message. All the data in the message is included. Its slowing my code down.
Is there some way I can turn these off - such as a command line parameter under “Run Configurations”, for example?
thanks in advance.

Update to a newer image, that was fixed a while ago:
