@girish Thank you. The Red Hat documentation was roughly how I was thinking of it and in that case I should be fine with 1GB of swap (as I am not suspending the server, etc...) although 2GB might be better.

However, if i look at my apps they say, "Cloudron allocates 50% of this value as RAM and 50% as swap.". If that is a hard rule then that might explain why my apps seem to be restarting, even ones that don't get a huge amount of load (eg; low visit website), as after 8 x 256mb apps my swap space is fully allocated.

Now, I am running 17 apps at the moment and according to System Info/System Memory this is using 3GB of memory out of "RAM (3.85 GB) + Swap (984.99 MB)" which would seem to me to be a reasonable headroom unless the swap rule is hard at which point I have (assuming 256mb apps) over 2GB allocated to swap and under 1GB available.

So, is the swap rule hard? Because then it would seem to me to mean I need to have the same amount of swap as RAM. In my case 4GB.

Hopefully that is clear and thank you for your former reply.

Weirdly, I have just been looking at libretime to set up a radio station with a friend. It would be cool to have it on Cloudron (and easier).

@girish Increasing the swap seems to have cured the problem. Additionally, there may have been a problem caused by a misreading of the amount of swap as originally on the Linode it said there was only 512mb but in Cloudron it said there was almost 1GB.

I have increased the swap from 512mb to 2048mb and I haven't received any app out of memory notifications since then so that seems to have cured it.

Thank you for your help.

@jdaviescoates I looked but there didn't seem to be any multiperson ones that could pump out an mp3 stream. I have another look though. Thank you.

@echokos Did youcome up with an answer to this. I am looking to do the same and I can deploy a LAMP stack or Surfer to do a single static site but at a cost of 256MB each. What I would like is to be able to use one Surfer or LAMP stack to serve many domains.

EG; 10 x static sites = 2560MB of usage in Cloudron whereas anywhere else I can serve 10 static sites with less that half that.

This might be outside the scope of Cloudron as it is a two application process but there is a multi network opensource application called Ferdi that relies on a server to hold the passwords and such.

Having the server available on Cloudron would enable people to have a multimessenger application where they are not giving away their passwords to be held by an unknown server/admin.

There is a docker setup here.

I resized my VPS up and now I have 1GB of swap and 4GB of RAM. As apps apply half memory to swap should I increase my swap to 4GB?
