Exception: Apartment::PoolCapacityReached

Inherits:
ApartmentError show all
Defined in:
lib/apartment/errors.rb

Overview

Raised when admitting a new tenant pool would exceed max_total_connections and no idle pool can be evicted to make room, under the :raise overflow policy. Distinct from PoolExhausted (a single pool’s connections) — this is the process-wide pool-count ceiling. See docs/designs/pool-admission-control.md.
