new scanner_service.go errors related to RPC? #140

Open ThomasBlock opened 1 month ago

ThomasBlock commented 1 month ago

My FCP is generally working fine now.

but there are periodically some strange errors. they appear over some hours, then there are no errors for some hours. i think its related to RPC.

SWAN_CHAIN_RPC = "https://mainnet-rpc01.swanchain.io"

level=error msg="503 Service Temporarily Unavailable: ..." func=Scan file="scanner_service.go:66"

so i tried my own swan-node.. seems good but now different error:

SWAN_CHAIN_RPC = "http://127.0.0.1:8545"

503, mainly errors that occur when using RPC to access chain data in a short period of time. Due to the retry mechanism, data will continue to be updated; database is locked has been fixed, and the lock timeout mechanism, the number of concurrent connections, and the change of synchronization data mode have been added.
