If you’re using a bitnami installation package we can’t assist you. Those installation packages are created by a third party and are completely unsupportable here. You’re going to need to ask Bitnami for assistance if you want to use their packages and you will continue to run the risk of such issues arising again in the future.
My recommendation would be to follow the standard installation guide and restore a backup of your site. Any sidekiq issues are likely to be resolved in the process.
