Have at least two users who are experiencing identical error with their Storms. They get white screen and an error message on top about lack of memory and suggestion to delete some file or apps. After hard-resetting the device they stop receiving their BES messages. So far the only solution I've found was to reactivate the device with Enterprise Server. Then everything is fine for a while. Are there any know issues with the OS the Storm is running or what can I do to alleviate this issue?

thank you
