# TooManyChildren (/docs/errors/chain/TooManyChildren)

`set_children` was called with more than 5 child hotkeys for a parent on the subnet. Trim the children list to at most 5 entries.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`limit_exceeded`](/docs/errors/limit-exceeded).
