Connection Pool Exhaustion in Development Workloads

Storybook utilizes on-demand builders to facilitate a rapid development cycle. Under heavy workloads or within complex component architectures, these builders establish network connections that may lead to connection pool exhaustion.

There is uncertainty regarding the internal mechanism that manages these connections and whether a configurable limit exists to prevent the environment from saturating available sockets during high-frequency hot module replacements (HMR) or large-scale story rendering.

What are the default connection limits for the on-demand builder? Is there a documented configuration to tune the connection pool size to prevent exhaustion in resource-constrained environments?
