Hello, We are using latest build of Wowza Streaming Engine (4.1.0.03) and Java version 1.7.0\_51 (64 bit) on a Windows 2012 R2 server with 32GB or installed memory, and Wowza set to “Production Level”. Until recently all worked fine, but last few days, I am getting the “java.lang.OutOfMemoryError: Java heap space” on a daily basis. The only thing changed lastly is that we started serving HD videos (2MB). An example link to such HD video: [http://www.kolhalashon.com/new/Media/PlayShiur.aspx?ShortName=0918-20141119-084935&Video=True](http://www.kolhalashon.com/new/Media/PlayShiur.aspx?ShortName=0918-20141119-084935&Video=True) The server has 8 application setup, 2 live and 6 VOD. Only one of these application serves the HD videos. Please urgently help us since this effects many users. Thanks, Eyal. ---
