Hi!
We Use Wowza Streaming Engine for VOD with Wowza Media Cache
Since we did the upgrade to 4.7.1 we see the following problem:
When performing VOD Files under high load the Server suddeny cant access the Media Cache Source.
I have to disable/enable the network Adapter, after that the Media Cache Source is available.
This error does never appear with version 4.3.0 (Im running this Version on a second Server it has the same load)
We monitored the open file handles of the Java process, it seems they constantly increase
How can we overcome this?
Regards robert
