Hello,

I’m using the 5$ droplet with phpMyAdmin 1-click installation and serving a REST API over apache2.

Couple hours after I restart my apache service, when I use the following command to view processes that use the most memory:

ps -eo pmem,pcpu,rss,vsize,args | sort -k 1 -r | less

I see a lot of the same processes that over time piling up and never being killed, hence filling up the memory to about 90% :

%MEM %CPU   RSS    VSZ COMMAND

 2.9  0.2 30016 500080 /usr/sbin/apache2 -k start
 2.8  0.1 28420 498072 /usr/sbin/apache2 -k start

 2.5  0.3 25952 497976 /usr/sbin/apache2 -k start

As soon as I run “systemctl restart apache2” all of these processes disappear and my used memory decreases by a lot.

And idea about what is wrong with my server?

Thanks in advance.
