For more context:
- Codeship (a CI tool) was connecting on the server in SSH and was running a command (this command calls php, postgresql, and has to log some things in a custom log).
- This command seemed to be blocked (no response, but no details on console)
- The served site (nginx, postgresql) was not responding on page that calls postgresql commands.
- I connected in SSH, restarted postgresql service, and the codeship script failed.
- Then everything worked again (postgreSQL is OK).
I searched in PostgreSQL logs, in Nginx logs and in php logs, but found nothing. So I started to dig into syslog. But I'm not an expert. These lines are the lines where I think the problem started but I'm not sure.
- What does these lines mean?
- If it has nothing to do with my actual problem, where should I search?
