Odd error, only has a problem turning something off

Every night I have a time rule arm my security alarm. That works fine. Every morning I have it turn off via a time rule and that fails every time now (it used to work very reliably).

In the openhab log file I see this at the time the alarm should have been disarmed:

2016-05-06 05:00:16.073 [ERROR] [.myopenhab.internal.MyOHClient] - Socket.IO error: io.socket.engineio.client.EngineIOException: websocket error

2016-05-06 05:00:16.073 [INFO ] [.myopenhab.internal.MyOHClient] - Disconnected from my.openHAB service (UUID = 0524ea43-5153-42fa-9aa7-6b93e1dd9b82, local base URL = http://localhost:8080)

All the other rules work and they persist through to myopenhab just fine. This one used to work as well. I did make a separate disarm rule to run based on the time to test things, and it worked!

Is there a way to delete an item from myopenhab so it can be re-created?
Does the error above mean anything to anyone?

Thank you for any suggestions you may have.
