Numerous NullPointerExceptions in AntMedia server logs (v2.4.3)

Question

Hi everyone,

While investigating the logs from our AntMedia server (v2.4.3) running in the Azure Kubernetes, we've come across numerous "java.lang.NullPointerException" records, sometimes even happening multiple times within one minute, which is to us worrying. So far, we haven't seen any disruption of service while the exception occurs, but still we're worried that eventually we will.

The AntMedia logs showing the exceptions: 

AntMedia-2.4.3-NullPointerException-logs.log

Could anyone explain why the exceptions are happening and whether we can/should do something about that in our AntMedia implementation?

Thanks in advance!

Hi @mustafaboleken,

It's been a while since last update here so I wanted to share our latest testing results regarding this issue. We've monitored the logs regarding this in the latest 2 AntMedia versions we received: v2.5.1 and v2.6.0-snapshot, and unfortunately it seems the issue persist.

According to the logs, some of the NullPointerExceptions happen around midnight each day, related to the redirecting the requests between different machines (like you previously said), but some happen during a day, and are connected to the streaming itself (i.a.enterprise.webrtc.WebRTCClient).

I'll share the most recent logs with you again so you can analyze it on our end and hopefully give some insight for us in terms of those exceptions being dangerous for the AntMedia server performance and its overall stability.

The logs can be found here:

ams-server-logs-2.6.0.snapshot-nullpointerexceptions.log

Thanks in advance again for looking into this!
