Has any had a problem when trying to start a MN, Error: could not allocate vin.
Just an update:
If you are running multiple masternodes with a passphrase on the wallet you will see this error.
To kinda fix it:
Step 1: Unlock Wallet with Passphrase
Step 2: Strat 1 Masternode
Step 3: Repeart for Each Masternode.
