when edge server have primary and backup origins, when the primary origin fails, the nDVR streams becomes unwatchable. The stream in interrupted every few seconds. I assume, that on every chunk, the primary origin is first queried, and this is the problem. This kind of messages appears in the log:
ERRORservercomment2017-05-0316:32:38-----72.066--------DvrStreamStoreBase.retrieveChunkFromRepeater[liveedge/definst/ch1.stream/ch1.stream.0] : e:HTTPDvrRawChunkReader.open: Invalid HTTP length[-1]: http://192.168.1.22:12346/liveorigin/definst/ch1.stream.0/ChunkTypes(9)/ChunkIndexes(65084).dvr
Is this a normal behavior, nDVR to not support multiple origins ?
P.S. If You try to watch the stream without nDVR ( without ?DVR ), the stream is OK.
