v3.2103.0

### Does this issue reproduce with the latest master?

Haven’t tried that.

### Steps to Reproduce the issue

```auto
var storeDB utils.SDB
type DeploymentConfig struct {
        Name string
        Version string
}
name := "testDC"
var dc utils.DeploymentConfig
dc.Name = "testMeta"
dc.Version = "00.00.0.init"

err := storeDB.Set(name, dc)
if err != nil {
  Log.Error(err)
  return err
}

type (
  SDB interface {
    Get(key string) (value *DeploymentConfig, err error)
    Set(key string, value *DeploymentConfig) error
    Delete(key string) error
    Close() error
  }
  StoreDB struct {
    db *badger.DB
   }
)

func (sdb *StoreDB) Set(key string, value *DeploymentConfig) error {
  err := sdb.db.Update(func(txn *badger.Txn) error {
    DBS, err := sdb.Get(key)
    if err != nil {
      Log.Debug_f("key [%s] not found: may be initial insert with key", key)
    }
    var updatedValue = *value
    mergo.Merge(&updatedValue, DBS)
    err = txn.Set([]byte(key), updatedValue.encodeDeploymentConfig())
    Log.Info(value.Name)
    if err != nil {
      Log.Error_f("Unable to set key [%s] with value [%s]\n", key, value)
      return err
    }
    return err
  })
  return err
}

func InitDB(dbFile string) (SDB, error) {
  bdb, err := badger.Open(badger.DefaultOptions(dbFile))
  if err != nil {
    Log.Error(err)
  }
  sdb := &StoreDB{
    db: bdb,
  }
  return sdb, err
}

```

### What Badger options were set?

badger.DefaultOptions

### What did you do?

Insert two key value pairs. The daemon has been running for approx. 12 hours.

### What did you expect to see?
