Hi everyone, I am using a VM (KVM) on CachyOS and for storage I am using a nvme WD_BLACK SN850X 4T.
My VM
2 Processors
4 GB Memory
2T Virtual Disk
I managed to sync the blockchain without problems, but when I try to sync the electrum server things don’t go well. I noticed the Electrum was restarting, then I checked the bitcoin core and it was down. Apparently it was in restart loop state.
Is there anything I can do to alleviate things for core? Maybe it’s too much IO?
Below is the log:
