Package: systemd-journal-remote

Version: 247.3-7+deb11u1 arm64

When i try to get the log file with the systemd-journal-gatewayd service thru an UNIX-SOCKET, the log ist flooded with the following meassages after the normal log entries:

Apr 23 10:07:00 home-assistant systemd-journal-gatewayd[16476]: microhttpd: Setting TCP_NODELAY option to ON state failed: Operation not supported

Apr 23 10:07:00 home-assistant systemd-journal-gatewayd[16476]: microhttpd: Setting TCP_CORK option to OFF state failed: Operation not supported

Apr 23 10:07:00 home-assistant systemd-journal-gatewayd[16476]: microhttpd: Failed to push the data from buffers to the network. Client may experience some delay (usually in range 200ms - 5 sec).

The only setting in the systemd-journal-gatewayd.socket is:

[Socket]

ListenStream=/run/systemd-journal-gatewayd.sock

I run Debian 11 on a Raspberry Pi 4, but the same problem occurs on Debian 11 running on a amd64 machine.

When i try the same on an Ubuntu 20 machine, the recived log is okay.

I am using Linux home-assistant 5.10.0-21-arm64 #1 SMP Debian 5.10.162-1 (2023-01-21) aarch64 on the Raspberry Pi 4

That sounds like either a problem in the kernel or the microhttpd library.

Can you try with the backport version as well [1]

Since those errors come for libmicrohttp, I'm going to reassing the issue
Checking the changelog of libmicrohttp, there are quite a few changes
regarding the handling of those options, see
https://git.progress-linux.org/users/daniel.baumann/debian/packages/libmicrohttpd/tree/ChangeLog

I assume, Ubuntu uses a newer version of libmicrohttp

yes, this is supposedly fixed in (at least) the current version in
testing/unstable, thus closing the bug.
