# 51124: Twilsock: Too many connections

Log Level: ERROR

## Description

Your application has opened more Twilsock connections for your account than the current limit allows. Twilsock is the persistent connection layer used by Twilio client-side SDKs such as Chat, Sync, and Notify. This error usually indicates that your application is creating too many simultaneous client connections or is not closing unused sessions correctly.

### Possible causes

* Your application is creating a new client instance each time a page loads, refreshes, or rerenders.
* Users are signed in from many browser tabs, devices, or sessions at the same time.
* Your application is not shutting down unused SDK clients when users log out or navigate away.
* Connection retry logic is creating duplicate connections after network interruptions.
* Load tests, bots, or misconfigured clients are generating more concurrent connections than your account is expected to use.

### Possible solutions

* Review how your application initializes Twilio SDK clients and make sure it does not create duplicate client instances unnecessarily.
* Reuse an existing client connection when possible instead of creating a new one for each action or view.
* Close or shut down SDK clients when they are no longer needed, especially during logout, session expiration, or application teardown.
* Check your retry and reconnect logic to confirm that temporary network failures do not leave old connections active while opening new ones.
* Validate expected usage across tabs, browsers, and devices to make sure the connection volume matches your application's design.
* If your traffic is expected and legitimate, contact Support to discuss your account limits.
