I have an apport-collect file saved that was run against the 4.6 kernel. I can upload it if you like; apport would not do anything with it since it was not a mainstream kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1584471 Title: Java threads produce OutOfMemoryError with 4.4.0-22 kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1584471/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1584471] Re: Java threads produce OutOfMemoryError with 4.4.0-22 kernel
apport information ** Tags added: apport-collected ** Description changed: 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 -Xmx1M option.
