ASIC Miner Monitoring Help & Support

Automatically Restart ASIC Miners (Watchdog & Auto Reboot)

Automatic restart of ASIC miners helps maintain stable operation, especially when a miner freezes, loses connection to the pool, or stops submitting hashrate. On this page, you will learn when restarting really helps, how automatic reboot works, and what limitations you should consider.

Why ASIC Miners Sometimes Need a Restart

Even stable ASIC miners can face situations where a device restart is required.

Common reasons:

• Firmware freezing
• Loss of connection to the mining pool
• Network connection failures
• Configuration update errors
• Temporary system overload

In such cases, restarting can restore normal miner operation.

What Is Auto Reboot or Watchdog?

The automatic restart (watchdog) feature allows the system to:

• Monitor miner activity
• Detect hashrate loss
• Respond to miner unavailability
• Perform a restart when necessary

This reduces the need for manual equipment monitoring.

When Automatic Restart Helps

Automatic restart is effective when:

• The miner freezes without physical damage
• The device loses connection to the pool
• Hashrate temporarily drops to zero
• Occasional network issues occur

In these cases, a restart can quickly return the miner to normal operation.

When Restart Will Not Solve the Problem

A restart will not help if the issue is related to:

• Physical hardware failures
• Overheating (in this case, cleaning the miner from dust may help)
• Faulty power supply
• Corrupted firmware
• Persistent network errors

In these cases, hardware diagnostics are required.

Best Practices for Using Auto Restart

To ensure automatic restart works properly:

• Do not set excessively short monitoring intervals
• Avoid frequent restarts without analyzing the root cause
• Monitor device temperatures
• Check network stability
• Use restart as a support feature, not as the main solution

Common Restart Triggers (Examples)

Automatic restart is usually configured based on events that indicate unstable miner operation. These events are called restart triggers.

Most common examples:

Hashrate Drops to Zero for a Certain Period.
If the miner stops submitting hashrate for a defined interval, the system can perform a restart to restore operation.

Miner Stops Responding on the Network
If the device becomes unreachable by IP or does not respond to monitoring requests, this may indicate firmware freezing.

Loss of Connection to the Pool
If the miner cannot connect to the pool for a long time or repeatedly loses connection, a restart can help restore stable operation.

Errors in Boards or Chips Operation
Some hardware failures can cause temporary shutdowns, and a restart may help return the device to working condition.

Important: Overly sensitive trigger settings may cause frequent restarts. This is not always helpful and can hide the real cause of the problem.
