High Connection Utilization

Last updated: 2022-01-21 19:55:36

    Error Description

    • Symptom 1: the connection utilization was high.
    • Symptom 2: connections couldn't be established.

    Common Causes

    • Connections leaked.
    • The configured maximum number of connections is too low.


    Check for connection leaks. For third-party network connections, there must be a finally block for execution; otherwise; non-standard code is prone to cause the problem where connections are not released properly.

    Troubleshooting Procedure

    Modifying code logic

    Check whether connections leaked, and if so, you can release invalid connections and fix non-standard code that leaked connections.

    Modifying connection configuration

    1. Log in to the TencentDB for Redis console, click an instance ID in the instance list, and enter the instance details page.
    2. In the Network Info > Max Connections parameter on the instance details page, click Adjust to adjust the maximum number of connections.
    3. In the pop-up window, adjust the maximum number of connections and click OK.

    If the problem persists, submit a ticket.
