Hello,

what are the main reasons for the wowza memory heap to increase?

This could help you, but send in a support ticket so we can accurately diagnose what is contributing to a very large Heap increase.

**TIP: Avoid reaching server overload.**

- Hitting bandwidth limitations and running out of memory are two common ways servers hit maximum capacity when streaming.
- To avoid overloads caused by limitations on server processing capability, you will need to know how many streams your server will need to process concurrently and how much memory this will require.

  

a. Consider a load test tool like [jMeter](https://jmeter.apache.org/).  
b. Distribute server load with [load balancers](https://www.wowza.com/docs/load-balancing-overview)  
c. Increase your processing power.  
d. Consider a hardware accelerator

I would also suggest tuning your Engine server for optimal performance:
