Hello,

I would like to know about Wowza heap release.

When I use StreamTarget function with HLS push then, the Wowza heap will increase up to 100%.

Therefore Wowza Streaming Engine will be uncontrollable by Wowza heap issue.

Would you tell me, how do I release the Wowza heap?

I have changed the following settings.

cupertinoMaxChunkCount

cupertinoPlaylistChunkCount

I’m using the following module as HLS push to S3.
