Hmm, considering you are using `filter-on=*` the above chain-state-db-size-mb seems low. There are 100 million trxs in the blockchain. Assuming a transaction is 500 bytes (the actual size should be higher and varies), it will cost you around 50 GB to index 100 million trxs. Not counting the fact that chain-state-db-size-mb is also used for the contract table (I don’t know know how much is the actual usage of RAM now but it can as big as the amount of bought RAM). If you don’t have that much memory and you just want to index the transaction, I think you can use the mongo db plugin which indexes the transaction in your mongo db instead.
