Validator not starting and stops sync

[acroca]

Similar to #792, but also stops sync.

---

This is a validator running in a EC2 box.

When it starts, its account had 2e+24 mtokens and 1000000000000000000 kUSD. It starts the process with the flag for the deposit set to 1e+24 tokens.

The validator syncs correctly with the devnet.

Once it syncs, the new balance is 1e+24 mtokens and 999999999999818674 kUSD

After syncing, it gets stuck and doesn't sync anymore

And of course is not validating, but it's running the validator...
