Error establishing a database connection

If you think that mysql server is the problem try to enable mysql log files. Also on which package your website runs? 512mb? You probably are running low on memory. By the way you can set up a cron job to restart your server

Hi there,

You need activate the swap in your droplet.

Please, follow this:

sysctl -w vm.drop_caches=3 or echo 3 > /proc/sys/vm/drop_caches sudo swapon -a or sudo swapon + partition_of_swap Ex: sudo swapon /dev/sda2

To permanent configuration, add it into /etc/fstab vi /etc/fstab and add: /dev/sda2 swap swap defaults 0 0 Reboot the droplet and be happy!

Hmm i cannot get this to work:

root@dailyblackcoin:~# sysctl -w vm.dropcaches=3 sysctl: cannot stat /proc/sys/vm/dropcaches: No such file or directory root@dailyblackcoin:~# sysctl -w vm.dropcaches=3 or echo 3 > /proc/sys/vm/dropcaches -bash: /proc/sys/vm/dropcaches: No such file or directory root@dailyblackcoin:~# echo 3 > /proc/sys/vm/dropcaches -bash: /proc/sys/vm/dropcaches: No such file or directory
