WowzaStreamingEngine won't start after upgraded to 4.8.0

[Sobari_Tanuwijaya1]

Hi,
I just upgraded wowza stream engine in my server from 4.7.7 to 4.8.0.
But now, the WowzaStreamingEngine won’t start.
If I check using /etc/init.d/WowzaStreamingEngine status, it always in stop status, when I check using systemctl status WowzaStreamingEngine, it said: active (exited)
After searching I found in one of the link saying that if I want to know more info, I better using startup.sh in the bin of Wowza installation directory, and when I using it, it gave me:

OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
Unrecognized VM option ‘UseParNewGC’
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Any ideas how can I solved the problem?

Thanks in advance for the help.

Here is the OS and Java in my server:

• OS: Centos 7
• Java: OpenJDK 11

There are other OpenJDK in my server, that is the OpenJDK 8, I change to OpenJDK 11 using alternatives -config java, when I issued the command: java -version it said:

openjdk version “11.0.6” 2020-01-14 LTS
OpenJDK Runtime Environment 18.9 (build 11.0.6+10-LTS)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.6+10-LTS, mixed mode, sharing)

Hello @Sobari Tanuwijaya

Please try removing “UseParNewGC” in your [install-dir]/conf/Tune.xml to see if it resolves this issue.

If not, please use the below link to open a support ticket for further review:

Ah, so it should be in that file (Tune.xml).

I had check the file but the only UseParNewGC that exists is surround by the comment.
But I solve the problem by changing the 21 line from:

<GarbageCollector>${com.wowza.wms.TuningGarbageCollectorConcurrentDefault}</GarbageCollector>

to

<GarbageCollector>${com.wowza.wms.TuningGarbageCollectorG1Default}</GarbageCollector>

following the explanation above that line.
And now the Wowza run as it should be.

So, Jason, thank you very much for the help.

This solution worked for me as well on Windows Server and Wowza version 4.8.24+4.
Encountered the problem on both Java JDK 11 & 12.
