Symfony version(s) affected

6.4.*

Description

My prod.log is full with always the same Line:

php.WARNING: Warning: Cannot modify header information - headers already sent by (output started at localpath/vendor/symfony/http-foundation/Response.php:1315) {"exception":"[object] (ErrorException(code: 0): Warning: Cannot modify header information - headers already sent by (output started at localpath/vendor/symfony/http-foundation/Response.php:1315) at localpath/vendor/symfony/http-foundation/Session/SessionUtils.php:52)"} []

The causing Line (SessionUtils.php:52) removes the cookie Header

header_remove('Set-Cookie');

and the error is generated while flushing the output buffer

ob_end_flush();

Is there anything i can do to fix this?
