The wallet's getblockcount reports 287403 blocks when it failed.
I am going to kill it and let it run again and see if I am 'stuck' on a block.
Wmikrut. I'm not sure what is causing your issues off hand? have you been able to get fully up-to-date yet?
To me it does sound like some type of wallet corruption. If it does crash again please try the following.
1) Navigate to %appdata%/HoboNickels directory
2) Rename your wallet.dat wallet-bad.dat
3) Startup the client with the parm -usewallet=""
4) After you are fully synced up. Let it sit for a while and see if it crashes. If not got 5, if so please report back here.
5) Using the load button, load up your wallet-bad.dat
6) If encrypted goto debug window/console and type usewallet bad walletpassphrase
999999 If not skip to 7
7) At this point I would send your coins from bad to ~Default. Do a few test sends first.
As always be sure to keep backups of your wallet.dat and other wallets offline as well.
Please let me know if you have any success.
