I am having a very similar problem on the Samsung Galaxy S3 running Ice Cream Sandwich. I can connect and disconnect reliably until the device the phone is connecting to is unavailable. After the connection times out or returns the rightful 'Unable to start Service Discovery' error (obviously due to the device being offline), I can never connect again to that device unless I power cycle the Phone.
I am also explicitly cancelling service discovery before all connections. I can exit and restart the Android app a million times as long as the device I am connecting to is still powered on and its Bluetooth radio is powered on. The minute the Android phone fails to see my target device, that's the end of the road until I reboot Android.
