nDVR conversion to MP4 failing

Hi,

I am trying to convert a single nDVR store using the REST API both with and without start/end parameters. When I query DVR converter status shortly after submitting the request, the state is SUCCESSFUL, but the result is a 160 byte file called <stream name>.partial.mp4. Here's what the converter status looks like:

{ "serverName": "_defaultServer_", "dvrStoreName": "CBS1HD_512.stream.21", "DvrConverterStore": { "dvrStoreName": "CBS1HD_512.stream.21", "audioAvailable": true, "videoAvailable": true, "isLive": false, "dvrStartTime": 20483412, "dvrEndTime": 22307100, "duration": 1823688, "utcStart": 1564001665995, "utcEnd": 1564003489671, "outputFilename": null, "conversionStatus": { "storeName": "CBS1HD_512.stream.21", "fileName": "/usr/local/WowzaStreamingEngine/content/CBS1HD_512.stream.21.partial.mp4", "state": "SUCCESSFUL", "statusCode": "NONE", "errorStrings": [], "startTime": 1563995848811, "endTime": 1563995849020, "duration": 209, "currentChunk": 0, "chunkCount": 887, "fileSize": 0, "fileDuration": 0 } }}

I looked at the access and error logs and didn't see anything indicating a problem.

Any ideas?

Thanks,

Alex.
