Thread: 88% memory consumption by java

  1. #1

    Default 88% memory consumption by java

    We are in the process of upgrading to Wowza Streaming Engine, but while we are still on 3.6.4, we are having memory retention issues consuming 88% memory and I thought I haven't tested this in 4.2, I am concerned that the same thing will happen there.

    I took a heapdump of the java process and surprisingly saw that the top consumers and heap retention are:

    Class Name	Shallow Heap	Retained Heap	Percentage	Retained Heap
    com.wowza.wms.httpstreamer.cupertinostreaming.livestreampacketizer.LiveStreamPacketizerCupertino @ 0x6a7b309f8	432	179717328	0.21372	179717328

    In summary, LiveStreamPacketizerCupertino and LiveStreamPacketizerSanJose are consuming 21% and 20% of the heap respectively and retaining. What could be causing this?

    I have httpOriginMode enabled being pulled by EdgeCast for viewership consumption.
