My zcasd 3.10 keeps crashing with fatal errors and fails to sync up. I’ve gotten all kinds of strange errors in the terminal and in the debug log. Here I’ll highlight the latest one because I recently increased the RAM and I don’t want to misattribute errors.
Previously I had some database errors and related crashes. I guess that was what prompted zcashd to reindex the database. When I launched it (without any flags), it reindexed ~20 GB of data, which suspiciously covered only the first 80,000 blocks. Then it continued from there with downloading blocks. A few minutes later it crashed with this terminal message:
Messages: - Error: Error: A fatal internal error occurred, see debug.log for details [Press Ctrl+C to exit] [Set 'showmetrics=0' to hide] zcashd: validationinterface.cpp:141: void ThreadNotifyWallets(CBlockIndex*): Assertion `pcoinsTip->GetSproutAnchorAt(pindex->hashSproutAnchor, oldSproutTree)' failed. Aborted (core dumped)
The end of the debug log had only this to say:
Corruption: block checksum mismatch *** System error while flushing: Database corrupted ERROR: ProcessNewBlock: ActivateBestChain failed
Any ideas what should I do?
If it helps, I’ve had
block checksum mismatch before increasing the RAM, but it was in the context of the following errors:
ERROR: ContextualCheckTransaction(): overwinter is not active yet ERROR: AcceptToMemoryPool: ContextualCheckTransaction failed
