This topic describes how to restart an ApsaraDB for Redis instance to release all connections when the number of connections reaches the upper limit or performance issues occur.

  2. In the top navigation bar of the page, select the region where the instance is deployed.
  3. On the Instances page, find the instance that you want to restart and choose More > Restart in the Actions column.
