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.
