Explorer losing old information #35

Closed WorldChainS closed 2 years ago

WorldChainS commented 3 years ago

I am facing an issue of losing old information on Epirus explorer, after it has been running for a while. For example, I set it up, it starts up with full information and after a day or two it loses old blocks, tokens, transactions, ... In MongoDB the data seems to be deleted.

When I do a new action on the blockchain, that one is visible until some time passes again.

@WorldChainS I have been trying to replicate your issue but in vain. I spin up a quorum node using npx then started flooding it with transactions (~100 transaction per block) etc. And I have been using the explorer against it and it seems to work fine. I am over 10k blocks and everything seems to be working fine. Maybe check docker allowed storage parameters as it might have been saturated.

I use the private network geth, the total block height is about 3 million, and the historical database is lost once a day on average

I am not able to reproduce. Would you please provide the steps to reproduce ? I have been running an instance for few days now and everything seems alright, no losses. Also, does the Db get truncated at the beginning ? Or you're loosing data from different places of the timeline ?

Closing. Please reopen if needed.
