Dollar Universe log shows some warning messages: Closing client connected without activity

Products

• Automic Dollar Universe

Issue/Introduction

This article explains the warning message 'Closing client connected for 61 minutes without activity' found in the Dollar Universe Universe.log and how to manage the idle timeout settings.

The following warning appears in the Universe.log:

| 2026-07-07 11:35:03 |WARN |S|IO |pid=####.####| u_io_thread_trt | Closing client connected for 61 minutes without activity

Environment

• Product: Dollar Universe (DUAS) version 7.x

Cause

The Dollar Universe IO server monitors active client connections. If a connection (such as an open UVC session or an API client) remains idle without sending traffic for longer than the configured limit, the IO thread force-closes the socket to reclaim resources.

The default timeout is governed by the dynamic variable U_IO_MAX_IDLE_CLI_MINUTE, which is set to 60 minutes by default. The warning triggers at the 61st minute of inactivity.

Resolution

This message is informational and does not impact DUAS job execution or core functionalities. To manage these warnings, follow these steps:

1. Identify the source of the idle connections. These are typically UVC WebConsole tabs left open or monitoring tools that do not disconnect cleanly.
2. Ensure users close UVC sessions when they are no longer in use.
3. If the frequency of these messages is undesirable, increase the timeout limit by modifying the dynamic configuration variable U_IO_MAX_IDLE_CLI_MINUTE to a higher value. No restart is required for this change to take effect.
