Peter can you make sure Jeff has access to the pcap?

I've been trying to carve a pcap out of the original pcap (140GB) that I was able to generate this issue with. So far have been unsuccessful , for starters I tried to carve out just "ftp" traffic, the resulting pcap was much smaller but could not reproduce the issue. Will keep trying and update the issue here.

If this issue is reproducible, then I suggest we try patching the following function -- adding an assert

int StorageSetById(Storage *storage, const StorageEnum type, const int id, void *ptr)
{
#ifdef DEBUG
    BUG_ON(!storage_registraton_closed);
#endif
    SCLogDebug("storage %p id %d", storage, id);
    if (storage == NULL)
        return -1;
    assert(storage[id] == NULL); // If not null, memory leak
    storage[id] = ptr;
    return 0;
}

Great ... this is to test a hunch. This was a place where it looked like there could be a memory leak related to the expectation handling.
