We are currently getting errors of this type in a Quarkus native app. The app works fine, and the errors are really sporadic (once a week, maybe?). Depending on usage, this app has a high consumption of RAM when generating big xlsx files with POI.

We understand that it’s memory related, but the error is not necessarily related to any execution (the last execution was about 30 minutes before the error, while the next one was 30 minutes later).

What we want to understand if this is a framework error (something that should be reported), a dev error (something we can fix/tweak), or if it’s just expected to happen.

• Quarkus 3.8.5
• Java 17
