Generally, you need to keep all wallets connected while your PeerGroup
is running. As soon as you disconnect a wallet, it will get out of sync.
You can replay out of sync wallets, but you'll need to reset these
wallets and all other connected wallets, plus remove the blockchain so
it can start from genesis (or an appropriate checkpoint if you use
checkpoints).
Bitcoinj doesn't scale to many wallets. The "one PeerGroup per Wallet"
approach has afaik never been tested; it's probably best to run each
such combination in a separate VM.
