Hi, Troubleshooting a memory issue on or Wowza server that eventually causes the server to run out of memory. Streams suffer as a result. Occurrences are mostly inconsistent. Sometimes the server will run for days/weeks without issue, however, last week there were two occurrences within a 24 hour period. RAM utilization is consistently above 60% with 1 inbound RTMP and 5-6 outbound RTMP streams. No transcoding, packetizers not in use are disabled. Only HLS, RTMP and RTSP are enabled. Server has 16GB RAM. Activity Monitor shows Java process consistently consuming between 9 and 13GB. Current settings: Performance Tuning\>Java Settings Custom Level Heap: 8000MB Java Garbage Collection Settings: G1 (Garbage First) Collector Thank you. Jorge ---

Hi, For others reading this thread, this problem was resolved when updating the Java version. Wowza Streaming Engine was configured to use Java 1.6 and when updating this to Java 1.8 the issue was resolved. Regards, Jason ---

Thank you Salvadore. I will package the log files and submit a support ticket right now. Looking at the memory graphs, it seems garbage collection is working properly, I see the heap usage fluctuating but utilization by Java process is consistently high. Jorge ---
