Been fighting with my node all day... Very strange, my computer suddenly lost all connectivity, can't login with ssh, lightning KO, can't even ping or be pinged by anything, but my node still running fine through tor 🧐
After rebooting it has been fine again for a couple hours, and then the problem occurs again.
Any idea ?

@Sosthene Was it already synced? I have extremely slow response times during syncing. Or were some OS upgrades running in the background?

@flexbit Yes it was synced. No OS upgrades in the background for sure (was Linux, not fucking Windows).
I'm suspecting it might be related to BTCPay, I had a BTCPay server running on the same machine. I turned it off yesterday and it seems to have solved the issue.

Ping @NicolasDorier
Do you see any reason for BTCPay to mess with host connectivity ? I'm sorry I can't provide you much information, if it happens again what should I look for ?

Ok forget about that, I made some invoices again with BTCPay just to see if I can reproduce yesterday's bug but no, it has been running smooth up so far, so it must not be BTCPay...

@Sosthene @flexbit I saw such kind of things happening when RAM or CPU was not enough. Might me?

@Sosthene @flexbit what host and config are you using?

@NicolasDorier @flexbit I’m on a home server, an old laptop, 4G of ram, CPU might be an issue, isn’t lightning a bit costly in CPU ?

@Sosthene @NicolasDorier @flexbit compared to running a bitcoin node in the first place, resource use of the lightning daemon is negligible
e.g. memory usage 100MB and a little bit of CPU usage only when something is done on the network, hardly ever for a few peers

@orionwl @NicolasDorier @flexbit
Ok, but still I suspect it is related to BTCPay in some way, because I turned it off for two days now and the issue didn't occur, everything runs fine now

@Sosthene @orionwl @flexbit I saw high CPU usage happening if you start clightning before Bitcoin is fully synched.

@Sosthene @orionwl @flexbit though if you use the docker deploy, it can't be this because I make sure things are synched before starting

@NicolasDorier @orionwl @flexbit sorry I've been a bit busy this week, in fact it is definitely not related to BTCPay server (or at least not directly), because it happened even when I turned off BTCPay.
I'm investigating more in depth my logs, I thought it might be because of lightdm service but still crashed even if turned off.
I think it might be network manager, still not sure
