Hey fabrice,
I’m still having some issue with my participation node; it got up to about 11 million blocks synced but now it’s stopped and I don’t know why. I was wondering if you might have any insight. I seem to be stuck on round 11912309.
I have ~150 Mbps upload/download speed. I am running my node on an 8GB Raspberry Pi 4 using Raspbian Lite. I do not have a firewall on this machine but it is behind my router.
I installed the software by following the steps under “Installing with Other Linux Distros”.
RAM and CPU usage are very low right now. Back when it was syncing, RAM usage was closer to 40%, and my CPUs were maxing out. I am using a 1TB SSD that only has about 900GB of free space left.
When I run ./goal node status -d data, I get the following:
Last committed block: 11912309
Time since last block: 0.0s
