Just opened 0.8.1 after having successfully opened it a few times and received:
"Error opening block database. Do you want to rebuild the block database now?"
I clicked OK. Here is the debug.log. What might have happened? It shut down cleanly last time.

Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

have you tried moving the data directory to some other drive, and starting bitcoin with datadir=d:\new directory\ ?

No, I reindexed it and it is working fine now. |

None of the raw values for the monitored attributes looks odd. I last ran the 2 hour long test 2,404 hours ago. Think it is worth running? Edit: Also perhaps a checkdsk /r is in order? |

No, seems ok. Edit: Also perhaps a checkdsk /r is in order?
Give it a go, I assumed you already tried that. |

Give it a go, I assumed you already tried that. Ok thanks, will run that tonight. So it is likely to be an HD issue I guess rather than client issue as nobody has reported it? |

Same problem, immediately upon upgrading from bitcoin-0.8.0rc1-win32 to 0.8.1, on Win7-64. Chose Cancel. The .sst file referenced did not exist, but no problem creating the .sst file with Cygwin "touch". Deleted the .sst file I had created, restarted Bitcoin-Qt, ran fine the second time, no further mention of .sst files in the debug.log. 2-month old SATA laptop drive with no problems.

Ran chkdsk /r overnight. It didn't detect any bad blocks, bad file records, or unindexed files. It did discover free space marked as allocated in the volume bitmap and it did clean up unused index entries/security descriptors.

I ran a long SMART test which took 2+ hours. I says the drive is in perfect health. So no explanation really for the error as far as I can tell.

I think the issue wasn't on your part, instead with the recent Bitcoin 0.8.1 reference client. Developers have tweaked DB parameters in order to comply with older 0.7 client limitations and it seems like LevelDB started complaining. It only affects 0.8.0 to 0.8.1 upgrade. Solution is given by @inglian a few posts up. Hope it helps. |

(Weird however because the issue didn't happen the first time I opened the client after the upgrade.) |

It's been a few hours now and I tried to open my bitcoin-qt client again. It's working now without any errors.
I'm on a brand new iMac, the blockchain is on a SSD and I just checked the disk integrity, everything is good.
So strange, I just don't know what was causing this.
