Subject: Bot Producing Random and Incorrect Responses ("Ol", "O", "A") - Issue Report

Hello NVIDIA Developer Community,

We are using the NVIDIA NeMo Guardrails framework in a system where a user-facing product interacts with a bot hosted via HTTP requests on a separate backend. While the bot operates as expected initially, it eventually starts producing random, incorrect responses such as "Ol", "O", or completely blank outputs.

This issue persists until we reset the hosting server and thread ID, which temporarily restores normal behavior. However, the need for frequent resets significantly impacts the reliability of our system. When the system resets, all goes well for a short period of time, and the problems surges again and persists until the next reset.

Example Behavior

At an undefined point during operation, instead of returning coherent responses to user inputs, the bot begins responding with seemingly random or nonsensical outputs like:

• "Ol"
• "O"
• Empty or blank responses
• Repeated system-level warnings and unrelated logs
• Sending literally intents to user

Details

• The logs for the affected sessions will be attached to this post for clarity and further investigation.
• The issue occurs consistently after the bot has been running for some time, though the exact trigger remains unclear.

Attached Logs

For better understanding, we are attaching a selection of logs captured during sessions where these issues occurred. The attached logs highlight examples of:

1. Incorrect or nonsensical responses.
2. Warnings and anomalies recorded by the system.

We would greatly appreciate any insights or suggestions from the community regarding the cause and potential resolution for this issue.

Thank you for your support!

Steps To Reproduce

I don't know. The server is going working well in 1-2 days, and then start to have those problems and errors.

Expected Behavior

The server completely normal like when it started.

Actual Behavior

Bot awnsering random, incorrect or blank responses.
