ERROR: ConnectInputs() : a471d0 mapTransactions prev not found 13ce12
ERROR: AcceptTransaction() : ConnectInputs failed a471d0
and what does this error mean?
I have that one too, not sure what it means.
EDIT: Just thought a bit about it, and maybe it means that there was an attempt to validate a transaction whose previous transaction in the chain hasn't been validated yet. Possibly a minor concurrency thing, not really an issue.
