Hello all,
I try to figure out why apache goes down every few days. I’m on Digital Ocean with Ubuntu Linux 16.04.3, Webmin version 1.872 and Virtualmin version 6.02. The last 3 weeks apache stops about every week and I have to start it again. My installation is clean, I have not added or changed anything. The most extreme thing I did is to increase space on digital ocean. What I can see on apache error log is:

It is a repeated pattern in my apache error log. I don’t know what all these mean and it would be great to show me some directions! Thank you in advance.
