lbrycrdd crashes on restart and needs to be reindexed to recover #134

Closed kaykurokawa closed 6 years ago

kaykurokawa commented 6 years ago

When restarting lbrycrdd, there has been reports of it crashing

a) https://github.com/lbryio/lbrycrd/pull/109

b) Grin reported this error when restarting a lbrycrd node: lbrycrdd: main.cpp:2112: bool DisconnectBlock(const CBlock&, CValidationState&, const CBlockIndex, CCoinsViewCache&, CClaimTrieCache&, bool): Assertion `pindex->GetBlockHash() == trieCache.getBestBlock()' failed

Happens at block 359949

This is a possible cause of this issue but not sure... https://github.com/lbryio/lbrycrd/issues/133

Just had this happen to my node:

lbrycrdd: claimtrie.cpp:2416: bool CClaimTrieCache::decrementBlock(insertUndoType&, claimQueueRowType&, insertUndoType&, supportQueueRowType&, std::vector<std::pair<std::__cxx11::basic_string, int> >&) const: Assertion `removeClaimFromTrie(itInsertUndo->name, itInsertUndo->outPoint, claim, false)' failed. Aborted (core dumped)

Below is the log

The post directly above was a false alarm, due to https://github.com/lbryio/lbrycrd/pull/160 not being downgrade compatible

@kaykurokawa Can this be closed? Or is this bug still happening?

alyssaoc commented 6 years ago

reopen if necessary
