Hello Mark,

Upgrading tcnative from 2.0.13 to 2.0.15 fixed it for me.
Just in case somebody else has similar issue.
The minimum Tomcat Native version was increased to 2.0.15 for 11.0.23.
The core dump shouldn't have happened but it looks like running with
2.0.13 triggers the core dump before Tomcat has a chance to realise an
incorrect version of Native is being used. Not sure why at this point.
Something to look into.
Mark
Core dump didn’t happen with Tomcat 11.0.22.
(Environment Ubuntu 24.04 LTS, amazon-corretto-21.0.8.9.1)
Thanks!

Betreff: [ANN] Apache Tomcat 11.0.23 Available
The Apache Tomcat team announces the immediate availability of Apache
Tomcat 11.0.23.
Apache Tomcat 11 is an open source software implementation of the
Jakarta Servlet, Jakarta Pages, Jakarta Expression Language, Jakarta
WebSocket, Jakarta Authentication and Jakarta Annotations
specifications.
The notable changes compared to 11.0.22 include:
- Align the rewrite conditions ornext flag processing with
mod_rewrite, which follows a purely sequential evaluation
strategy.
- Ensure that malformed HTTP/2 messages that should trigger a
stream reset do so, rather than triggered a connection close.
- Add replay protection to the EncryptInterceptor. This is a
breaking change for the EncryptInterceptor.
Please refer to the change log for the complete list of changes:
http://tomcat.apache.org/tomcat-11.0-doc/changelog.html
Downloads:

Enjoy!
