Redis BUSY Redis is busy running a script

Redis is busy running a Lua script, and the command cannot be processed.

When encountering the error "BUSY Redis is busy running a script," the immediate action you can take as a user is:

  1. Identify the Long-Running Script: Use the command SCRIPT KILL if the script running is not performing any write operations. If the script is modifying data, killing it might not be safe, as it will result in a partial update.
  2. Check Current Operations: Execute SLOWLOG GET to see if there are any slow operations that might be causing the system to be busy, and identify any patterns or specific commands that are taking longer to execute.
  3. Monitor System Metrics: Although directly not a command, if you have access to the monitoring tools or metrics, check the CPU and memory usage of the Redis server. High usage might indicate that the server is under heavy load, contributing to the BUSY state.
  4. Evaluate Command Stats: Run INFO COMMANDSTATS to get statistics on the commands executed by the server. This can help identify commands that are called frequently or take a long time to execute, which could be related to the issue.

Remember, if the script cannot be safely killed or if the situation does not improve by investigating and taking action based on these commands, it might be necessary to wait for the script to complete or consider contacting someone with administrative privileges to intervene directly.
