Similar happened to me today, it's happened once before, around 6-8 months ago but my Core Wallet crashed again today, think Windows did something fucked up without my permission & when I got home the mouse pointer was stuck & nothing worked.
Now I've got to reindex again which will take me about 2-3 days.
Not happy.
Does this still happen with version 0.13.1
huh... not good
, use this to reindex if you have 16GB of ram and at least a quad core processor.
bitcoin-qt --dbcache=8192 --reindex
it will speedup the rebuild a lot (in my machine usually the entire process take 30 hours, with this it only took 8 hours to do that but it will use about 10GB of ram and a lot of cpu time)
achow101 give me this recommendation (at the begining of the post) and worked fantastically, i can wait 8 hours, but not 30 hours!!!! hehe
hope it helps a little
