can't assign value to header, header is already committed

After upgrading Lucee to the latest stable (6.2.2.91), some request (and only in production) throw this error:

Summary

Error:
can't assign value to header, header is already committed

Anyone else noticed this problem? Any idea, what to check or where to look? The issue occurs 3-5 a day, different users, different times, always the same function (but the function is called very often..) Any idea what to log in production? Thanks for any hints!

Ubuntu 24 LTS, Tomcat 11, Lucee 6.2.2.91, cfwheels 2.5.1, mariadb 10.11.

Hi @michaeldiederich, thanks for the report and the environment details.
We’ve tried to reproduce this but haven’t been able to trigger it locally yet. Since it only happens intermittently in production, a bit more context would really help. I suggest you to please have your tests to latest 3.0v, as we have already fixed with those issues. For 2.5.1, we are no longer providing any further support. Thank you
