I have three RTSP streams coming into my Wowza server, which is then doing audio-only transcoding and then broadcasts them. Occasionally, perhaps once a day, a stream will get stuck. By that I mean that when I request the Flash stream the video will start to play for a second or two and then stop. Because the stream is from an IP camera that puts a timestamp in the image, I can see that the video is old and must apparently be cached. Restarting the stream in the StreamManager immediately fixes the issue. Going back from the last time I restarted a camera, the mentions of the stream in the access log just prior to the restart are as follows: ```auto 2012-05-23 08:31:34 CDT comment server INFO 200 - RTPSessionDescriptionDataProviderBasicRTSPWorker.p rocessResponse: command:OPTIONS response:RTSP/1.0 200 OK status:200 handled:false - - - 96085.83 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:36 CDT comment server WARN 200 - CupertinoPacketHandler.handlePacket[myapp/_definst_/camera.stream]: Timecode out of order [video]: 7715643858:7715644369 - - - 96087.558 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:36 CDT comment server WARN 200 - SanJosePacketHandler.handlePacket[myapp/_definst_/camera.stream]: Timecode out of order [video]: 7715643858:7715644369 - - - 96087.558 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:36 CDT comment server WARN 200 - LiveStreamPacketizerSmoothStreaming.handlePacket[myapp/_definst_/camera.stream]: Timecode out of order [video]: 77156438580000:77156443690000 - - - 96087.558 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:36 CDT comment server WARN 200 - SanJosePacketHandler.handlePacket[myapp/_definst_/camera.stream]: Timecode out of order [audio]: 7715643487:7715644450 - - - 96087.683 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:36 CDT comment server WARN 200 - CupertinoPacketHandler.handlePacket[myapp/_definst_/camera.stream]: Timecode out of order [audio]: 7715643487:7715644450 - - - 96087.683 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:36 CDT comment server WARN 200 - SanJosePacketHandler.resetStream[myapp/_definst_/camera.stream][2:11]: Timecodes jumped back in time. - - - 96087.954 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:36 CDT comment server WARN 200 - LiveStreamPacketizerSmoothStreaming.resetStream[myapp/_definst_/camera.stream][0:11]: Timecodes jumped back in time. - - - 96087.954 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:36 CDT comment server WARN 200 - CupertinoPacketHandler.resetStream[myapp/_definst_/camera.stream][2:11]: Timecodes jumped back in time. - - - 96087.954 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:37 CDT comment server WARN 200 - SanJosePacketHandler.handlePacket[myapp/_definst_/camera.stream_aac]: Timecode out of order [video]: 7715643858:7715644369 - - - 96088.324 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:37 CDT comment server WARN 200 - CupertinoPacketHandler.handlePacket[myapp/_definst_/camera.stream_aac]: Timecode out of order [video]: 7715643858:7715644369 - - - 96088.324 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:37 CDT comment server WARN 200 - LiveStreamPacketizerSmoothStreaming.handlePacket[myapp/_definst_/camera.stream_aac]: Timecode out of order [video]: 77156438580000:77156443690000 - - - 96088.324 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:37 CDT comment server WARN 200 - CupertinoPacketHandler.resetStream[myapp/_definst_/camera.stream_aac][0:11]: Timecodes jumped back in time. - - - 96088.325 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:37 CDT comment server WARN 200 - SanJosePacketHandler.resetStream[myapp/_definst_/camera.stream_aac][0:11]: Timecodes jumped back in time. - - - 96088.325 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:37 CDT comment server WARN 200 - CupertinoPacketHandler.handlePacket[myapp/_definst_/camera.stream_aac]: Timecode out of order [audio]: 7715643583:7715644578 - - - 96088.325 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:37 CDT comment server WARN 200 - LiveStreamPacketizerSmoothStreaming.resetStream[myapp/_definst_/camera.stream_aac][0:11]: Timecodes jumped back in time. - - - 96088.325 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:37 CDT comment server WARN 200 - SanJosePacketHandler.handlePacket[myapp/_definst_/camera.stream_aac]: Timecode out of order [audio]: 7715643583:7715644578 - - - 96088.326 - - - - - - - - - - - - - - - - - - - - - - - - - 2012-05-23 08:31:37 CDT comment server WARN 200 - LiveStreamPacketizerSmoothStreaming.handlePacket[myapp/_definst_/camera.stream_aac]: Timecode out of order [audio]: 77156435830000:77156445780000 - - - 96088.327 - - - - - - - - - - - - - - - - - - - - - - - - - ``` I assume that this is the reason the stream got ‘stuck’. That being said, my memory is hazy whether similar warnings preceded earlier stuck streams. I see that some other forum posts here refer people to the [Troubleshooting live streaming issues](https://www.wowza.com/docs/troubleshoot-live-streaming) page when they have timecodes out of order. However, it’s not clear to me which change I should make, especially since I can’t reproduce the issue and waiting ~24 hours for it to randomly pop up again is a pain. 😉 Should I enable the server side sort buffer? While I have nothing specifically against buffering, since I’m more interested in moving on from any problems whenever they occur I’m happy to just automatically drop packets and/or reconnect if that’s the best way to keep the streams up for as much as possible. I guess that would make transcoding hard, though… Thanks. ---

Hi Try using the module found here, [https://www.wowza.com/docs/how-to-enable-advanced-monitoring-and-resetting-of-mediacaster-streams](https://www.wowza.com/docs/how-to-enable-advanced-monitoring-and-resetting-of-mediacaster-streams) It may fix the problem Jason ---

Wow, I don’t know how I totally missed that. Thanks, I’ll try that now.
