Hey, we have an issue with one of our client umbraco installations. We're using Umbraco 11 in combination with blobstorage for media storage. However it seems something is going wrong after a while and the post add file call hangs.

Looking at the code itself it seems a semaphore is used so I suspect this isn't released at some point causing our issue. However there is nothing in the logs indicating what is actually going wrong. So we're quite unsure how to proceed with debugging this issue or if there is a bug, we're also not doing anything custom on media saving and are unable to reliably reproduce it. Could anyone help with giving pointers as to where to look? The blobstorage itself is also not indicating any issues.
