Hi all.
I am running Ubuntu 16.04 (through regular updates and upgrades) on an HP DL380 with dual hex-core Xeon 3.47GHz cpus and 96GB RAM.
I upgraded this system a week ago, and started getting Java OutOfMemoryErrors (unable to create new native thread) from Wowza Streaming Engine. I tried older versions of Java (7 and 6 oracle versions) and they improved it, but did not fix it.
When I stopped the Wowza service from the command line, the service command would hang until I killed the java process.
I booted my system into the 3.16.0-41 kernel that was still there, and everything works as it should (no more OutOfMemoryErrors). I have not tried the 3.16 kernel with Java 8 OpenJDK; it is still running on Java 7.
Did something change drastically with the thread modules between the 3.16.0 kernel and the 4.4.0 kernel?
Wowza starts Java with the -Xmx10000M option.
One of the log entries for this error is:
WARN server comment 2016-05-20 23:55:21 - - - --5405.152 - - - - - - - - Unexpected exception.: java.lang.OutOfMemoryError: unable to create new native thread|at java.lang.Thread.start0(Native Method)|at java.lang.Thread.start(Thread.java:714)|at org.apache.mina.util.NewThreadExecutor.execute(NewThreadExecutor.java:34)|at org.apache.mina.transport.socket.nio.SocketIoProcessor.startupWorker(SocketIoProcessor.java:104)|at org.apache.mina.transport.socket.nio.SocketIoProcessor.addNew(SocketIoProcessor.java:83)|
Thanks.
