WebSocket Router: maxActiveConnections

maxActiveConnections caps the number of active WebSocket connections held by one light-gateway process.

• Type: Positive integer
• Default: disabled
• Disabled by: blank, null, or 0

maxActiveConnections: 1024

The limit is process-wide across routes handled by this WebSocket router; it is not per path, user, client IP, or gateway cluster. Each gateway replica keeps its own counter. A permit is acquired after routing, authorization, rate-limit, and upstream target selection, and is released when that request context ends.

When the process is at the limit, a new upgrade is rejected with HTTP 503. Use maxUpgradeRequestsPerSecond as the complementary control for bursts of upgrade attempts that may fail before becoming active connections.
