> copy_c? is this going to be freed after mainloop iteration?
Using copy_c to attach it to entry, so the msgb gets deallocated together with entry (see /* Limit list size */ block below).

> When is this list cleared or getting smaller?
If a bts gets deallocated (maybe possible at runtime via VTY?), then the list also gets deallocated because it is attached to the bts with talloc. Other than that, the list does not get cleared or deallocated as it would make the VTY command for reading the entries useless.

The size is limited in rx_fail_evt_rep().
