I have set up a few new headless Ubuntu servers.

:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 22.04.1 LTS
Release:        22.04
Codename:       jammy

After a while they work, I try to schedule a restart but It returns error.

:~$ sudo shutdown -r 8
Failed to set wall message, ignoring:No buffer space available
Failed to call ScheduleShutdown in logind, no action will be taken: Transport endpoint is not connected

Sometimes, it works after a few tries. I checked htop, and df -h I couldn't see any problem.

I have enough space on the HDD

df -h

and RAMs are used only %10 (128GB)

For a long time, I have not been resolving this problem. I appreciate your help.

Your provided details show you're well behind on applying security fixes; as a fully-upgraded 22.04 system will report itself as 22.04.3 (https://fridge.ubuntu.com/2023/02/24/ubuntu-22-04-2-lts-released/ shows the ISO release of 22.04.2, but installed systems upgraded to that in the week+ before the ISO release & you've not applied fixes to that level).

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
