+There is a known issue with the version of curl currently shipped with Alpine 3.19 and 3.x kernels, causing an endless loop to hang containers, usually on startup. The 3.x kernel line has been End of Life since 2017, but some prebuilt systems such as older Synology NAS units are still running it. At time of posting, around 10% of our images have already been rebased to Alpine 3.19 and are therefore affected by this issue, and this number will continue to rise over the next few months.
+
+While a fix has been applied to the affected upstream library we do not have an ETA for if or when it will find its way into the version of curl shipped with Alpine 3.19.
+
+### Workaround
+
+As a workaround you can revert to an older tag from before the image was rebased to Alpine 3.19, but please be aware that older tags do not receive updates. Refer to the Changelog in the Readme to see when the change was made for a given image. For Unraid users this will require you to edit the container and under the Advanced options change the Repository to append the required tag.
