How to Fix MongoDB Error Code – 82 – NoProgressMade

MongoDB is a popular open-source NoSQL database that offers high performance, scalability, and flexibility. However, like any software, it can encounter errors that may disrupt its normal operation. One such error is MongoDB Error Code – 82 – NoProgressMade. In this article, we will explore the causes of this error and provide solutions to fix it.

Understanding MongoDB Error Code – 82 – NoProgressMade

MongoDB Error Code – 82 – NoProgressMade occurs when a MongoDB operation fails to make any progress within a specific time limit. This error typically happens during long-running operations, such as index builds or large data migrations. When MongoDB detects that no progress has been made within the allowed time, it throws this error.

Possible Causes of MongoDB Error Code – 82 – NoProgressMade

There are several potential causes for this error:

• Insufficient System Resources: If the system running MongoDB does not have enough resources like CPU, memory, or disk space, it can lead to slow or stalled operations, triggering the NoProgressMade error.
• Lock Contention: MongoDB uses locks to ensure data consistency. If multiple operations are contending for the same lock, it can result in a deadlock situation, causing the error.
• Network Issues: Slow or unreliable network connections between MongoDB nodes can cause operations to stall, leading to the NoProgressMade error.
• Hardware Failure: If there is a hardware failure, such as a disk failure or network card malfunction, it can disrupt MongoDB operations and result in the error.

Fixing MongoDB Error Code – 82 – NoProgressMade

To resolve the NoProgressMade error, you can try the following solutions:

1. Check System Resources

Ensure that the system running MongoDB has sufficient resources. Monitor CPU, memory, and disk usage to identify any bottlenecks. Consider upgrading hardware or optimizing resource allocation if necessary.

2. Optimize Queries and Indexes

Review your MongoDB queries and indexes. Poorly optimized queries or missing indexes can cause slow operations. Use the MongoDB explain() method to analyze query execution plans and identify areas for improvement.

3. Increase Operation Timeouts

If the NoProgressMade error occurs during long-running operations, you can increase the operation timeouts to allow more time for completion. Adjust the maxTimeMS parameter for the specific operation or consider using the noCursorTimeout option for cursor operations.

4. Check Network Connectivity

Ensure that the network connections between MongoDB nodes are stable and reliable. Check for any network issues, such as high latency or packet loss. Consider optimizing network configurations or upgrading network infrastructure if necessary.

5. Monitor and Troubleshoot Lock Contention

If lock contention is causing the NoProgressMade error, monitor the MongoDB logs for any lock-related messages. Identify the operations involved and analyze their resource usage patterns. Consider adjusting concurrency settings or redesigning the application logic to minimize lock contention.

6. Verify Hardware Health

Check the health of the hardware running MongoDB. Monitor disk health, network interfaces, and other hardware components for any signs of failure. Replace any faulty hardware to ensure smooth operation.

Summary

MongoDB Error Code – 82 – NoProgressMade can occur due to various reasons, including insufficient system resources, lock contention, network issues, or hardware failures. To fix this error, it is essential to check system resources, optimize queries and indexes, increase operation timeouts, ensure network connectivity, monitor and troubleshoot lock contention, and verify hardware health.
