- Server operating system version
- AlmaLinux 8.5
- Plesk version and microupdate number
- 18.0.57 #2
I recently started having unexpected issues with my Plesk Obsidian based server running on AlmaLinux 8.5. The server had been up and running for over 180 days without issue with over 160 domains. The past three days it's started showing a white page, that says 'No input file specified' for one of the domains. I can refresh the page a couple of times and it'll eventually load, until you try to go to the next link or page, then the same thing happens. It'll log errors AH01071: Got Error 'Primary Script Unknown' and AH01071: Got Error 'Unable to open primary Script' /var/www/vhosts/domain_name/httpdocs/file.php ( Too many open files ). I can restart the server and it runs fine until about the same time the next day. The domain is running on PHP 7.4.33 as an FPM application under Apache. Any help or insight would be greatly appreciated. The server was runing 18.0.54, but I updated it to 18.0.57 #2 to see if it might resolve the issue. I ran the diagnosis and repair utility on the domain and it didn't find any issues.
