Hello,
Many times, we see smaller sized droplets run out of memory due to the number of processes that are running. This can cause slow connections, services to crash and overall unpredictable behavior.
Potential solutions are:
-
Upsize to a larger server. We recommend at least a 1GB droplet for any server utilizing a MySQL database.
-
Enable swap (search for 'swap' in our articles https://digitalocean.com/community)
