We talked about it before, several times.

Some years ago one of the gods accidentally caused an experimental jump of a magnitude in the node IDs. That means the current max ID is far bigger than the real number of nodes.

He later patched the calculation to take the gap into account, but it fails if the search takes longer than 10 secs IIRC.

You'll find multiple threads about this when using super search (sic)

HTH!
