Topic: Crashes routinely while syncing :-( (Read 952 times)

I also had a similar issue, for me it sporadically was crashing just after starting up with v14.1.
I had to wait for a minute or two before interacting with the UI and then it worked fine. Might have been some threading issue if the block check, the sync/communication worker and the user want to access data at the same time.

Thanks, I fixed it by defragging, which worked for a bit, that'd be a boot time defrag, and then when it crashed again later I moved the Bitcoin directory, copied it and pasted it elsewhere and changed the settings so Bitcore used the newer version. So, disk problems then! If yours keeps crashing in the same place, it's probably worth assuming it's the hard drive and trying another one if you have it or moving the directory. I'm up to 2 years and 7 weeks now so it's motoring along ok, Thanks for your reply :-)

One of my machines appeared to crash at 2 years and 48 weeks as well and I have no idea why.
You could try downgrading from version 13 to 12.2 (the archives are avaliable on the official bitcoin website).

If that fails and you need an alternative you could try something like electrum.org (so you have control of the private keys) or I think there are some lighter versions of bitcoin core (and also pruning avaliable so a smaller amount of the blockchain is stored).

It runs along happily for a while, then crashes, then crashes straight away when I try to restart it. I have to reindex after that. I believe it's version 13. I tried 14 but it didn't work well, can't remember why. I've seen threads saying that 14 will hammer your hardware and, well, it's an old machine. It's running on an old Dell which frankly I'm doubting is up to it. It's Windows 10 - the great unknown! There's plenty of available disk space. I've reindexed and restarted a few times and I have a suspicion that it's crashing at around the same period which suggests a disk problem. Next on my list is to note where it crashes and then try again with the bitcoin directory in a new location. At the moment it's got up to 2 years 48 weeks behind. Thanks for your response :-)

What does it do exactly. Does it start up and instantly shut down or do you shut it down?

It could be a problem with this:

Which looks like an external connection. Is there free disk space avaliable? If you reindex do you get the same problem (also is this the most recent version of core or a few versions early)?

Keep getting this now :-) Drive problems, do we think? I've run checkdisk, all seems ok.
