Hi,
I have set up PostgreSQL according to this link:
https://www.cherryservers.com/blog/how-to-install-and-setup-postgresql-server-on-ubuntu-20-04 <https://www.cherryservers.com/blog/how-to-install-and-setup-postgresql-server-on-ubuntu-20-04>
The issue is that after a few hours of operation, even if I don’t access
the database at all, the Postgres process fails:
*christan@vultr*:*~*$ systemctl status postgresql*
*●*postgresql.service - PostgreSQL RDBMS

Moreover, it looks like there is some process stuck into some eternal
loop, eating up 4 cores:
*christan@vultr*:*~*$ ps -ef | grep postgres
*postgres*3342383 1 0 2022 ? 00:00:00 FzXlkULu
*postgres*3344758 1 99 2022 ? 3-14:39:11 OElid7Dp
*postgres*3419125 1 18 13:57 ? 01:17:03 tracepath
christan 3463982 3462489 0 20:44 pts/0 00:00:00 grep --color=auto
*postgres*
The above and the below look weird.
Is this machine open to the world?

*christan@vultr*:*~*$ top -p 3344758

Doing just systemctl postgresql doesn’t restart the process, I have to
manually kill all the above processes then do systemctl restart.
Lastly, in the journalctl I see the following logs:
Dec 31 21:33:35 vultr.guest sudo[3340093]: *pam_unix(sudo:auth):
co**nversation failed*
Dec 31 21:33:35 vultr.guest sudo[3340093]: *pam_unix(sudo:auth): auth

Dec 31 21:33:52 vultr.guest crontab[3341588]: (postgres) LIST (postgres)
What am I missing here, maybe I have to make sure that postgres user has
sudo rights?

Antonis
