Front-end struggling on VPS with 1GB of RAM
The VPS in question is the Oracle Cloud Free Tier, running on Ubuntu 20.04 Minimal. Rebooting the VPS instance temporarily solves the problem, until the RAM goes back up to 100% usage again.
How many devices do you have? What's the message volume? Are you sure there are no other processes running on the server? What database are you using?
How many devices do you have?
Just one.
What's the message volume?
If you mean in terms of location updates, it's 1 every 10 seconds.
Are you sure there are no other processes running on the server?
I'm sure there are other minimal processes running in the background, but I highly doubt their usage will be high. I'll double-check in a few hours.
What database are you using?
I'm using MySQL.
Sounds like it should be working fine, given those details. Have you checked CPU usage?
Have you checked CPU usage?
I have previously, and the CPU usage hasn't ever reached 100%.
We are running a lot of small scale servers with 1GB of memory and never had any issues, especially with a single device. There must be something wrong with the hosting. Maybe they restrict some resources.

@Scrub, I can confirm your problem with Oracle VPS and Ubuntu 20.04 minimal...
Works for some days but, after that, CPU usage goes high and the server is unusable.
New instances had the same problem again...
I had the same problem for days until I created a 2Gb swap file and enabled it.
No problem since then

P.S: Thanks! you've make me remember that I enabled a 'uptime log' script running each 60s ;)
Don't need it anymore.
Hey.
Unfortunately, when trying to view the front-end on a VPS with 1GB of RAM (1Gb/s bandwidth), it hardly is able to present the login page. And often times it times out.
Are there any ways to optimise the memory usage?
Thanks.
