Hello,
Since 1.27.0, it looks like my producer node with 8GB RAM is running at 92% RAM. Is this normal and do you think running at this level consistently will do any harm?
If so, I might upgrade have to upgrade to 16GB RAM (would prefer not to atm since it is almost double the price for an instance that tier on AWS) 
Thank you,
David
Yes, the node use 7g in new version but I think it will be tunned in future. U can use SWAP option ;
Ps what are the prices for 16G?
Hi @Alexd1985
Thanks for the reminder that there was swap memory. I just added 8GB of swap memory.
Appreciate the reminder! 3 year for 8GB is roughly 800-1000 USD (depending on the type of reserved instance - standard or convertible) and 1600-2000 USD for 3 years.
Also, for those who find this post and have not set up swap, here are instructions below:
Create swap file and enable:
sudo fallocate -l 8G /swapram
sudo chmod 600 /swapram
sudo mkswap /swapram
sudo swapon /swapram
echo '/swapram none swap sw 0 0' | sudo tee -a /etc/fstab
Check that it worked.
sudo swapon --show
Increase swappiness of swap by editing the sysctl.conf:
sudo nano /etc/sysctl.conf
Adding lines below to bottom of sysctl.conf file
vm.swappiness=10
vm.vfs_cache_pressure=50
Reboot
sudo reboot
Cheers,
David
wow, so expensive, I used contabo the cheapest vps I think and never had an issue… they recently opened a data center in Singapore
Yeah, it was a big sacrifice to host it on AWS and I did so mainly for exposure to a top cloud provider for the experience and the 99.99% guaranteed uptime.
I think digitalocean was slightly cheaper than AWS. I’ll take a look at Contabo for other projects (maybe another relay node 
) Thanks for sharing though!
Cloud used to be cheaper but now it gets expensive really quick 
that’s why I moved my nodes home 
David,
Thank you.
Regarding the Swappiness:
Q: Do I need to reboot the server for these to take effect?
Found it …
I checked the ubuntu docs and it says.
