It's true, by default Digital Ocean's droplets are created without any swap space. Actually, they recommend not to enable it on their solid state disks: "Although swap is generally recommended for systems utilizing traditional spinning hard drives, using swap with SSDs can cause issues with hardware degradation over time. Due to this consideration, we do not recommend enabling swap on DigitalOcean or any other provider that utilizes SSD storage. Doing so can impact the reliability of the underlying hardware for you and your neighbors. If you need to improve the performance of your server, we recommend upgrading your Droplet. This will lead to better results in general and will decrease the likelihood of contributing to hardware issues that can affect your service." (from https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-me...) I guess it's my choice between being cheap or being a good customer.

Barton et al,
The output from the "free" command in Rubeno's original post shows that he has no swap space.

How much swap space do you have allocated?
There are probably a lot of libraries loaded where Koha is only using a function or two, and I believe that MySQL is very aggressive about loading data into memory, not all of which is used.
Conventional wisdom is that swap will slow down the system because you have to page things back into memory... but conventional wisdom doesn't take into account the fact that there are a lot of things that get loaded into memory but not used. Swap is good, folks!

Excerpts from Rubeno Fernández's message of 2018-03-19 07:12:29 +0100:
How much memory do you need to run Koha? I run a database with about 22000 records on a virtual server on
Digital
Ocean
with 1GB memory and very low usage, but the server is crashing very
often.
We're running Koha 17.11.02 on Linode (Debian 8) with 2 GB of RAM, and our library has about 25000 item records. So far we haven't had any out of memory problems. _______________________________________________ Koha mailing list http://koha-community.org Koha@lists.katipo.co.nz https://lists.katipo.co.nz/mailman/listinfo/koha
