Wowza Streaming Engine causes continuous high load on the server even when not use, higher than any other services or accounts on server. This still occurs after upgrading to 4.1.0, build 12602, released on September 11, 2014

Did not experience such results with previous versions (Wowza Media Server 2,3…) where process CPU was around 3%.

With the new Wowza version server load averages jumped from 0.5% to 4%.

Hi,

Please can you zip up your conf/ logs/ transcoder/ and manager/ and send to support@wowza.com. We can then try and determine the issue with you.

Tried to reduce Wowza load on system by halving default threads which reduced load with a quarter.

Also turned off service WowzaStreamingEngineManager . We start it manually only when needed, to prevent additional troubleshooting hassle with load.

Not using transcoder. Mediacache was also disabled.

But Wowza is still only process on system with 2 digits CPU load, although there are only few connections (as noticed in fresh access logs):

Rest of processes use 0% CPU.

Zipped everything suggested:

```auto
zip -r debug conf/* logs/* transcoder/* manager/*

```

Archive is 48M because manager folder takes 73M (with 46M in manager/temp).

Will send this to support email.
