A few months ago, I encountered an issue while using rsync to back up data from my MacBook to a NAS. rsync would appear to be running normally for a while and then suddenly hang indefinitely. The terminal output showed it syncing files as usual, and then it just… stopped. There were no error messages, and rsync didn’t exit. Initially, I thought it might be a large file transfer or an unstable network connection. However, I discovered that if I killed the process and ran the rsync command again, it would resume smoothly from the file where it had previously stuck. This happened several times in a row!
