sony camera remote api setCurrentTime call sometimes results in http response 500
<p>I'm using the sample app included with some additions. Sometimes, the call to the setCurrentTime API results in an IOException in the SimpleHttpClient because of an error 500, at other times, it works just fine a minute later with exactly the same code. What could cause this?</p>

<p>Here's a log excerpt from when it's not working:</p>
