Cron causing web server restart

    Greetings,

    I am using AIOWPS under LiteSpeed. I have LiteSpeed configured to restart automatically to fix 503 errors. Pretty much every hour during the day at 26 minutes past the hour I get an email notification informing me that LiteSpeed has been restarted to resolve the 503 error.

    This time corresponds pretty much exactly with the time of the cron job. Note, this restarting only started yesterday. AIOWPS was only installed yesterday – the cron time is set to run every hour at 24 minutes past the hour.

    I have added a noabort directive to .htaccess – figured it may be a cause, but surely this cron is just a cleanup job for the db right, from what I understand?

    Is there anything I can do or enable/set to stop this happening every hour? When the cron starts, the site gets very slow, process usage is very high, up until the point when the web server process is bounced.

    That’s rather strange that a wp-cron even would cause that issue. I haven’t seen such a problem before.

    The following are the only tasks that wp-cron schedule can potentially kick off in the aiowps plugin:

    – DB backup
    – file change detection scan
    – DB cleanup

    Maybe you could try disabling the first two of the above features to see if that stops the 503 issue. (the “DB cleanup” can’t be disabled atm because it happens automatically)

    Thanks for your reply – DB backup is already disabled actually, but I’ll certainly try the disabling the file change detection scan and keep you posted!

    Hm, actually the file change detection scan is set to only run once every 4 weeks ??

    Any other ideas of what might be happening?

    If those aiowps features are disabled and the problem is still happening hourly it is probably not being caused by aiowps.

    Are you running any other plugin which requires wp-cron? (maybe a backup plugin such as backupbuddy or similar?)

    Was some kind of maintenance mode enabled when you saw these issues?

    @cagsmith you might like to try the following plugin WP Control. It will help you find out what cron jobs are running and even manage them.

    Kind regards

    Hey there, I was using WP Crontrol – it’s how I discovered the AIOWPS cron job which is running at the time the server restarts. No other backup plugins or cron jobs running at this time ??

    I will need to try disabling the pluging to see if it resolves the issue.
