hi. thanks for ur reply. i compared it with ordinary successful open log. error started from that. also error message said to reindex as ur suggestion. will i redownload the whole blockchain if i reindex...??
I think if your wallet is set to pruned mode and you use -reindex it will only download the latest blockchain and delete old blockchain you recently downloaded.
I don't know what would be the outcome after you use the command above but better add
prune=(N) at bitcoin.conf file so that it won't download the whole blockchain.
