Bitcoin knots rpc spins forever and never finishes health checks but you look at the Bitcoin logs seem to be fine it’s all caught up & even mempool works. I’ve exhausted anything I could find to help alleviate the problem (increased rpc timeout, que etc) even if I’m only running Bitcoin knots it still doesn’t complete health checks in order to narrow down any other issue causing it not to finish. There was a little promise right after I increased everything…worked for about 20 min & then started again. Again the logs appear to be fine. Claude says there is a 0.3.6 for this exact thing but I was unable to find any such file out there. Thank you kindly for your assistance.
Umbrel Bitcoin UI works perfectly as well strange indeed lucky me
What hardware are you running StartOS on and what version of StartOS are you running (0351 or 040)?
the most latest free one I could get 0.3.5~1
running on an old 2015ish (I think it’s a core i5) laptop 16GB RAM 5TB sata (conventional) hard drive & I think the startOS side seems fine as far as booting up and then allowing login from webpage/other apps work smoothly the Umbrel Bitcoin UI shows the Green Dot from the installed services page & display’s 100% blockchain sync’d/ mempool gui works as well (took about a month to sync the blockchain which seemed longer trust me)
If you go into Bitcoin Knots and then into Config, then click Save without changing any settings, does this solve the issue for you? If not, try restarting the server and seeing if this, after the “Save” action, changes anything.
I’ve tried the config save thing didn’t really do much of anything if restarting the server would/should I shut down bitcoin first & then restart?
I don’t see why it would be a problem either way really. So no need
tried bitcoin config open and made no changes then save and restarted bitcoin waited about 30+ min before checking; same results; restarted the server waited almost an hour no change again
For clarity on your first post: There is no 0.3.6 of StartOS. Claude AI fabricated that version. 0.3.5.1 is the latest stable. We shifted to 040 beta versions and are on 040.beta9 right now with beta10 being worked on currently.
The only thing standing out at me is that the spinning HDD might be the culprit here. The HDD is fine for storage but Bitcoin’ random I/O patterns are exactly what spinning drives struggle with most.
Could you check your Bitcoin Knots logs and see if there is any additional information in there like errors, etc…?
yeah strange the bitcoin log doesn’t show any errors at all looks perfectly normal…there was a datum notify error but thats obviously going to do that while health checks fail, either way I reset datum for now until I can get the health checks I mean IF of course as you pointed out being a conventional hdd I did notice the I/O was darn near 50% from the system of startOS I’m sure this is the cause
Perhaps you can send a screenshot of the health check and the logs from Services > Bitcoin Knots > Logs > DOWNLOAD.
Feel free to DM it to me or @OKIN

That line there indicates that your are synced to the latest known tip. So you’re right, the logs look fine afaict.
As for the health check, can you visit the Services > Bitcoin Knots page and share that screenshot? It will have a more detailed breakdown there under the label “Health Checks” – at a glance from the main services dashboard that you posted, it looks like it’s ok, but you said the RPC health check “spins forever”? Is that where you’re talking about that happening, or somewhere else?
What did you set your “increased rpc timeout, que, etc” to?
Yes the health checks never finish
increased rpc timeout, que to their most maximum allowed settings and that did work for about the first 20 min or so after making that adjustment but then same thing with not being able to complete health checks
What are the literal values that you set the timeout and queue to?
Which ISO of StartOS 0351 did you use from here?:
startos-0.3.5.1-39de098_x86_64-nonfree
rpc server timeout: 300
threads: 64
work queue: 256
