Looking at dmesg I see a bunch of lines like this:
Stopping User Runtime Directory /run/user/118...
[ 55.241395] systemd[897]: user-runtime-dir@118.service: Failed to
connect stdout to the journal socket, ignoring: Connection refused
[ 55.249255] systemd[1]: run-user-118.mount: Succeeded.
Started Run anacron jobs.
[ 2846.911055] systemd[2236]: anacron.service: Failed to connect stdout
to the journal socket, ignoring: Connection refused
[ 2846.915533] systemd[1]: anacron.service: Succeeded.
Those are just two example of "failing to connect stdout to the journal
socket"
