This happens while syncing

minkcrypto-zz commented 5 years ago

I think this crash happens when syncing blocks with big transactions ( maybe 100 recipient or something ), it doesn't happen with original iquidus.

uaktags commented 5 years ago

That doesn't quite make sense with what's happening in that code segment:

https://github.com/uaktags/explorer/blob/06d8229a97548633dd1de8b013b37b22f93c28bd/lib/database.js#L822-L831

What this is saying is that there's no such thing as "block.tx" which means that "block" itself, if it is an actual JSON object containing a block, doesn't include any transactions.

can you get it to output the block itself console.log(block); and perhaps the blockhash as well?
