Thread: AMF Exception

  1. #1

    Default AMF Exception

    Hello, just for feedback

    i had a pretty big videoconferencing session today (about 1000 people connected to the same app instance), and i noticed this error in the logs:

    constructor AMFDataObj(ByteBuffer)[70:86] : java.io.UTFDataFormatException: malformed input around byte 0|at com.wowza.wms.amf.AMF3Utils.deserializeString(AMF3Utils.java:286)|at com.wowza.wms.amf.AMF3Utils.deserializeString(AMF3Utils.java:193)|at com.wowza.wms.amf.AMFDataItem.deserialize(AMFDataItem.java:401)|at com.wowza.wms.amf.AMFDataItem.<init>(AMFDataItem.java:176)|at com.wowza.wms.amf.AMFData.deserializeInnerObject(AMFData.java:340)|
    i wasn't there during the session, so i don't know if it had consequences.

    update: i got some feedback and apparently from that moment the sound became unstable and shutdown, and the sharedObjects gone mad (using particularly the textchat module)
