After 1.27.0 - Producer Node excessively high RAM?


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) :confused:

Thank you,

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



sudo reboot



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 :smiley:) Thanks for sharing though!

Cloud used to be cheaper but now it gets expensive really quick :stuck_out_tongue:

that’s why I moved my nodes home :slight_smile:

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.

  • Reboot to make sure the new swap gets activated properly at startup
