When I rebooted my droplet it completely locked down. I cannot access with SSH or FTP. I cannot even ping the domain on it. I can only access with the “Console access” from my DO account.
Analysis of the apache error log learns that it rebooted three times with a few minutes. Each time that produced the following entries: mpm_prefork:notice AH00171: graceful restart requested. Doing restart mpm_prefork:notice AH00163: Apache/2.4.29 (Ubuntu)mod_fcgid/2.3.9 OpenSSL/1.1.0g configured – resuling normal operations core:notice AH00094 Command line: ‘/usr/sbin/apache2’
After that I got: mpm_prefork AH00169: caught SIGterm, shutting down suexec:notice suEXEC mechanism enabled (wrapper: /usr/lib/apache2/suexec) mpm_prefork:notice AH00163: Apache/2.4.29 (Ubuntu)mod_fcgid/2.3.9 OpenSSL/1.1.0g configured – resuling normal operations core:notice AH00094 Command line: ‘/usr/sbin/apache2’
That was the end of it.
This is a fresh Ubuntu 18.04 droplet with Virtualmin installed. I am not aware of having done anything extraordinary since the previous reboot: just installing PHP modules, changing php.ini a bit and uploading files.
