Thanks for all your inputs, you were right to think that an issue was recently introduced between 2.4.26 and 2.4.27. The offending commit is: > commit 7156740285745e73a52982b8b01ce8975f3fd633 > Author: Willy Tarreau <w...@1wt.eu> > Date: Thu Feb 8 18:15:23 2024 +0100 > > BUG/MEDIUM: cli: fix once for all the problem of missing trailing LFs > Which was just backported in 2.4.27 The issue doesn't lie in the patch itself, but since patch was initially written for the 3.0, it turns out that despite applying without errors, it was not compatible with older versions (< 2.8) without a small adaptation. You can find the regression fix for the 2.6 here (with more information about the bug in itself): https://git.haproxy.org/?p=haproxy-2.6.git;a=commit;h=219ce3bce43acb4ba2b4a45a6a988cfa0cb11da9 It will be backported in 2.4, and should be included in the upcoming stable releases. Thanks again for your help, we really appreciate it. Regards, Aurelien
