An investigation on StoRM databases @ CNAF has shown that there are many (thousands) PtP requests stuck in the IN_PROGRESS state for a long amount of time. StoRM currently lacks a mechanism to gargabe collect this requests, so administrators are forced to do the cleanup "by hand" by accessing the database.

The request GC mechanism should be extended to collect all requests that are stuck IN_PROGRESS for a configurable amount of time.
