Question

I am observing a rather interesting behavior. I have upgraded from Jetty9.x to Jetty 10.0.24

My security team is running a HTTP2 Fuzz workload from Defensix on this Jetty server.

While doing this, we have observed that the application POD in Kubernetes goes OOM killed. But the heap memory used by the application is just 2Gb (total POD limit is 16G).

I have been able to isolate almost everything else. Could this be due to related to Jetty?

Could this be due to non-heap usage of my application? The jcmd command shows almost 10G in "Others".

Can Jetty consume so much non-heap memory?

Any pointers would be much appreciated.

Thanks

Jetty 10 is at end of community support, see:

• EoCS (End of Community Support) for Jetty 10 / Jetty 11 - January 2024 #10485

Please upgrade to Jetty 12 and report back if the issue is still occurring.

Thanks @sbordet , I understand Jetty10.x is EOCS. And I plan to upgrade to Jetty12.x when we move to Java17.

But for now any pointers on this would help since this is a production issue and must be fixed before we plan for upgrades.

Thanks!

@dev-chirag if you need production support for an EOCS release, you must contact Webtide for commercial support.
