LND 0.16.2 high cpu and regular restarts

Support and Troubleshooting
#1

Since upgrading to 0.16.2 my lnd is just not healthy. It runs OK for a bit, then I get a lot of these:

[INF] HLCK: Health check: chain backend, call: 1 failed with: health check: chain backend timed out after: 30s, backing off for: 2m0s

and occasionally (every hour or two) it’s unlucky and reaches three failed attempts and restarts lnd:

[CRT] SRVR: Health check: chain backend failed after 3 calls
[INF] SRVR: Sending request for shutdown

CPU usage on lnd becomes really high, bitcoind seems fine.

I’m wondering if it is related to… https://github.com/lightningnetwork/lnd/issues/7675

Anyone else experiencing similar issues with 0.16.2?

Checking out issue,

In the meantime in your Lightning Node advanced settings you can turn on this setting if not on already to see if that helps with load times:

Thanks. I’ve set that, which reduced DBs by around 2x. Sadly same issue occurred after an hour uptime :frowning:

Can you share a debug log file?

It doesn’t allow me to share the log (‘Sorry, new users can not upload attachments.’), but I’ve since realised i’m on too low a spec Pi4 (2gb); recommended these days is 4gb. Upgrade arrives tomorrow which will should improve matters.

Today is a good day; 7 hours since last LND restart. 0.16.2 definitely hit performance, but 0.16.3 with its wallet upgrade + higher mem will hopefully sort me out.
