Assertion failed or Corrupted wallet?

Hello Grindsters!

Are you experiencing "Assertion failed" error message and, or a corrupted wallet, after your system hung, auto-restarted or crashed?

Assertion failed!

Program: ...

File:scr/kernel.cpp

line:780

Expression:pindex->pprev||pindex->GetBlockHash()==(!fTestNet ? hashGenesisBlock:hashGenesisBlockTestNet)...

This particular error quoted above is caused by a corrupted database and the only solution is to re-download your blockchain but here is what I do to save data and time, since the auto-backup doesn't backup the blk0001.dat file.

I regularly backup the following files in my gridcoin research folder.

1 - blk0001.dat, 

2 - wallet.dat (mainly after creating a new address), 

3 - gridcoinresearch.conf 

4 - televeldb folder 

This is done after exiting a perfectly working session. 

Anytime I experience any major issue that require re-downloading the blockchain, I just restore those files. Please be sure that you are not backing-up a forked blockchain.

Good-luck.
