Title: trouble syncing new install? Post by: arklan on October 02, 2018, 12:53:16 AM so, on a new windows install and formatted hard drive I've installed 16.3 and am trying to sync for the first time. it's getting stuck at about 15%. stays on the same block with no progress for hours. tried restarting the whole process by closing bitcoin core and deleting to data folder (separate hard drive from the install) and it happened again, about 15%, but a different block. the first time I had closed the client and replaced the newly made wallet file with my old one, but the second time I did not.
any thoughts? i can just leave it, but a block shouldn't be taking 6+ hours to download and process, should it? Title: Re: trouble syncing new install? Post by: achow101 on October 02, 2018, 01:15:57 AM Please post your debug.log.

Title: Re: trouble syncing new install? Post by: bob123 on October 02, 2018, 08:37:01 AM This might be caused by a hardware issue.
Can you verify that your CPU is not overclocked and cooled properly ? And also check your hard drive (i.e. S.M.A.R.T. values) and your RAM (i.e. memory test). Title: Re: trouble syncing new install?

And also check your hard drive (i.e. S.M.A.R.T. values) and your RAM (i.e. memory test). definitely not overclocked, never do that. has the factory cooler and i just blasted everything with air sunday night. recently ran a bunch of memtests, both using windows built in diagnostic and memtest86. results were... inconclusive? i've been having random hard crashes where the whole system locks up for over a year now. but recently finally replaced the SSD and reinstalled windows, as well as the video card. after that and blasting the insides with air sunday it's been running fine. HDD looks to have a warning about some sectors if i'm interpreting HDDscan correctly. not surprisingly, it's 8 years old. i'll do some investigation on that and probasbly replace the drive when i can.

Usually these kind of issues are due to bad memory. If memtests were inconclusive, you might want to consider replacing or removing some of your RAM to see if you can identify which modules are bad.recently ran a bunch of memtests, both using windows built in diagnostic and memtest86. results were... inconclusive? i've been having random hard crashes where the whole system locks up for over a year now. but recently finally replaced the SSD and reinstalled windows, as well as the video card. after that and blasting the insides with air sunday it's been running fine.

Title: Re: trouble syncing new install? Post by: emordin on October 05, 2018, 05:52:27 AM I'm having the exact same issue, where my download got stuck at 22%... I'm downloading it to a 2 TB My Book Essential external drive , thru a Ubuntu VM with 3gb ram and 2 processors set aside for it. Also I got to 22% because i had a consistent 8 connection download, now its steady between 1 -3 connections and the download is very slow to the point of years.
Any ideas on what I should do? Title: Re: trouble syncing new install? Post by: bob123 on October 05, 2018, 06:03:02 AM I'm having the exact same issue The EXACT same issue ? Then something is wrong with your hardware.. But most probably you do NOT have the exact same issue.. Create a new thread, explaining your problem and post your debug.log. Without the log, no one can determine your issue (and therefore also can't give you hints to solve it). Title: Re: trouble syncing new install? Post by: HCP on October 05, 2018, 08:17:11 PM It could quite possibly be an issue caused by attempting to use an external disk (via USB) from a VM.
Additionally, 3gig is a relatively low amount of memory... And 2 cores from what I assume is a 4 core processor? ??? You're basically kneecapping your setup in every conceivable way... Low ram, low cpu, low speed HDD, low speed interface to HDD and then doing it all via a VM!!?! :o Is there any chance you can try it with a more "direct" approach? Perhaps an Ubuntu live USB setup? That might at least help you eliminate the VM (and low ram/cpu) as the source of your issues. |
