Auto restart VPS when high-load?

[Jovani]

Hey Guys,
I don't know why this was happened when my site downtime for 5 seconds around 9 or 10:AM each 2 days a time on my VPS, it's using Centos.
My site is using wordpress CMS, don't have more plugins on it, traffic is stable without increasing suddenly.
How to know it caused by my web system or my web server? how to detect the problem?

So you VPS automatically restarts at 9-10am every other day?

Do you have any cron jobs? Scheduled backups, updates, etc?

Maybe I used cron jobs on my site, I will check them

What are scheduled backups, updates? can I have them on my VPS an how to check them are enabled?

Schedule backups are pretty much a software or cron job setup to backup your files at specific time + date. Is this taking place around the time your server goes down?

You mentioned your downtime is 5 seconds.... Is your site actually not reachable during those 5 seconds or is it just what your up time "report" is stating?
