hi. guys . I want to watch the transactions related to accounts. I use the com.ripple.client.Client class to do that . and use client.subscriptions.addAccount(accountID) to subscribe the my account. if subscribe 1000 accounts it works fine. but if subscribe 50000 account. i can not receive the transaction from onValidatedTransaction callback . is there a limit size? is there any way i can config on the rippled side?
