acquiring certificates ensure the corresponding domain names are set as per the standard [DNS naming conventions](https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/#pod-identity) in a Kubernetes StatefulSet (for a distributed MinIO setup). Then create a secret using ```bash kubectl create secret generic tls-ssl-minio --from-file=path/to/private.key --from-file=path/to/public.crt ``` Then install the chart, specifying that you want to use the TLS secret: ```bash helm install --set ...

	go z.cleanupStaleMPCache(ctx)

	return z, nil
}

func (z *erasureServerPools) cleanupStaleMPCache(ctx context.Context) {
	timer := time.NewTimer(globalAPIConfig.getStaleUploadsCleanupInterval())
	defer timer.Stop()

	for {
		select {
		case <-ctx.Done():
			return
		case <-timer.C:
			z.mpCache.Range(func(id string, info MultipartInfo) bool {
