Hi, welcome to iMore.
Yes. This happens when you are trying to download an app or movie or song that is bigger than the free storage you have on your device.
As there is not enough storage available, iOS starts clearing cache from apps in order to complete the download. If the cleared storage is not enough, the download will stop and you will have to free storage yourself by deleting content from your device.
If you have any further questions, please join our forum. We're happy to help.
