PHP Pool Page Fails to Load

Support

I got a report of a site not working, and when seeing if PHP was the issue whilst impersonating the site, I went to the PHP Pools page, and received an Internal Server Error. Tailing the php-fpm logs revealed teh following stack trace:

I don’t think all your migrations finished. See Sites down with 503 Service Unavailable with PHP pool page giving an internal server error - #9 by msaladna

That did it. You think anything else might have been left incomplete? I’m open to some preventative measures if you have any suggestions.

upcp will run any pending migrations as it works its way through the update backlog. As long as it completes without issue then everything ought to be current.
