Dash Core worked for months, now crashes

I've been running Dash Core for 6 months or more on my Mac mini (OSX 10.13.4 High Sierra), no problems. A couple of weeks ago it started crashing within a minute of starting it up. There was no obvious change just before it started to fail. I have some Dash in the wallet, 5 maybe. I updated to 0.12.2.3 from 0.12.2.1 (I think) a few days ago, but it still crashes. It starts up, says loading block index, sometimes displays 8% or 12% or 16%, then after a minute just crashes.

Any suggestions?

The beginning of the error log (IDs deleted) is:

Thanks for any help.
 
Hi there, the first thing you should do is make sure you have a backup of your wallet.dat file, just in case. Then maybe try deleting all the .dat files EXCEPT wallet.dat in your application data folder? For macOS this should be ~/Library/Application Support/DashCore
 
Thanks for the suggestion. I made a copy of wallet.dat, then deleted all the .dat files except wallet.dat. I then opened DashCore and the same thing happened, namely it started to load the block index then crashed after a minute.

I rebooted, same result.
 
was there an update for High Sierra recently ?
 
OK, thanks for trying that. Let's see if we can get a developer in here to look at the error log you posted... @thephez you got a minute?
 
Pls copy all the text it gives you inside the crash dialog box into a new file. Also find debug.log file in ~/Library/Application Support/DashCore. Put them in one folder, select both, right click, "Compress 2 items". This should create Archive.zip with these 2 files inside, pls send this zip file to me via email - [email protected]

Files zipped and emailed just now. Thanks very much.
 
Hmm... looks like your blockchain data files are corrupted. Pls remove blocks/ and chainstate/ folders in ~/Library/Application Support/DashCore and try syncing from scratch.

Aha! I deleted those folders, fired it up, and now it's syncing up. Looks like normal behaviour. Thank you. I'll post again, one way or the other.
 
Looks good now. It crashed once after about 80,000 blocks, but afterwards sync'd up fine overnight. I removed almost all the Dash to another wallet, er, just in case. Thanks very much guys for the rapid help.
