Hi,

HAProxy 2.9.2 was released on 2024/01/11. It added 37 new commits
after version 2.9.1.

A major issue about the zero-copy forwarding in TCP mode was fixed in this
release. A regression was introduced to the 2.9.1, blocking connection
closure on producer side and leading to loop consuming all the CPU. It is
pretty easy to be impacted by this bug. However, there is a workaround which
consists of disabling the zero-copy forwarding in TCP mode by setting
'tune.pt.zero-copy-forwarding' global option to 'on'.

Of course, the setting must be set to 'off' to disable it... Thanks Aurélien for noticing it !
