M_RESOURCE_LIMIT_EXCEEDED

The request cannot be completed because the homeserver has reached a resource limit imposed on it. For example, a homeserver held in a shared hosting environment may reach a resource limit if it starts using too much memory or disk space. The error MUST have an admin_contact field to provide the user receiving the error a place to reach out to. Typically, this error will appear on routes which attempt to modify state (eg: sending messages, account data, etc) and not routes which only read state (eg: /sync, get account data, etc).
