Dash Core wallet keeps crashing

[Itzak]

I just purchased addtional dash and added them to my wallet, then after they were confirmed it crashed. Dash Core just keeps crashing now. I even upgraded from 12.1 to 12.1.2 but no better. What should I do to fix it? I was unable to attach a file to this post so inserting error txt below. BTW the file in the log exists and is not locked.

Tried make a copy of the .dat file and place it on desktop and try open it from there ? Might be OneDrive space issue since your .dat file got bigger after transfer.

No dice, tried your suggestion. However I have over 800GB free of a 1 TB OneDrive space. I'm starting to think the block db is corrupted and I will have to reload the entire block chain again.

Is OneDrive online storage of microsoft ? https://onedrive.live.com

 

[Itzak]

Yes. It is a local folder which backs up to MS Onedrive cloud. I never had this issue before but as a test I turned off the OneDrive client and restarted Dash Core. So far it's run for several minutes. It is reindexing the blocks on disk.

I turned off the OneDrive client

aha.

 

[Itzak]

It finished indexing the blocks and all seems normal now with OneDrive turned off. Guess that was it.
