I had that problem on my old node, which was the main reason for the hardware upgrade. I think I was just running low on memory. Something was causing it to freeze up.

How is your uptime so far?
Almost 100% except for two days ago when the router it’s on went out and I rebooted before I realized what the problem was, and then LND decided to rescan every single UTXO, which took 5 hours. 😬
Thats great. Yeah, I wouldnt count that as it’s a different issue.
I switched from Primal address back to my Alby address, which sends zaps to my node. Maybe that was staining it somehow.
