Hi, I’m trying to transfer the RTMP stream with the metadata using FFmpeg to the Wowza Media Server. But, when WMS received the RTMP stream, it gives out lots of WARN logs as following: … LiveReceiver.startDataPacket[1200000222\_l/_definst_/1400006087]: Data packet sync issue. LiveReceiver.startDataPacket[1200000222\_l/_definst_/1400006086]: Data packet sync issue. LiveReceiver.startDataPacket[1200000222\_l/_definst_/1400006087]: Data packet sync issue. … Anyone knows the reason? and is it possible to get memory leak because these WARN logs? Please help. ---

Hello! Thanks for contacting Wowza Forums! What version of Wowza are you running? Here is an article on injecting metadata into Wowza for RTMP. have you implemented this? [HERE](https://www.wowza.com/docs/how-to-inject-cue-points-or-metadata) For us to better look into the issue, if you have further questions, I would suggest opening a support ticket [HERE](https://www.wowza.com/support/open-ticket).
