Re: [jetty-users] Native memory leak in 9.4.x fixed in 9.4.26

[Greg Wilkins <gregw@xxxxxxxxxxx>]

Scott,

thanks for this heads up.  26 did include a fix for a TLS timeout issue in https://github.com/eclipse/jetty.project/pull/4446  which could be related.  

cheers

This is more of an FYI, but I thought it was worth pointing out. I've observed a pretty massive native memory leak in 9.4.x since a fairly early version of that branch. This is running natively, exclusively HTTPS, directly exposed to clients, and it leaked a native buffer somewhere frequently enough to observe unbounded RSS growth on Linux under Java 11.

I had done some minimal tracing and got some evidence of the leak but hadn't yet filed a bug about it due to the complexity of gathering enough evidence to be actionable.

I just happened to upgrade to 9.4.26 and the leak appears to be gone.

I thought it was worth noting in case it's obvious to the devs what change fixed the leak, and if not, well, you fixed something important. ;-)

Diffing 25 and 26 only suggests a couple of likely areas of change that could have fixed it.
