Redis LOOP Detected infinite loop

Redis detected an infinite loop, typically in Lua scripting.
  1. Identify the Process Causing Loop: Use redis-cli monitor to monitor real-time commands and identify repetitive patterns that might indicate a loop.
  2. Check Memory Usage: Execute info memory to check if there's a rapid increase in memory usage, which might indicate an infinite loop storing data.
  3. Slowlog: Run slowlog get to identify slow commands that might be contributing to the loop.
  4. Client List: Execute client list to see if a particular client/connection is sending a large number of requests, potentially causing the loop.
  5. Kill Suspicious Connections: If a specific connection is identified as problematic, use client kill <ip:port> to terminate that connection.
  6. Script Debugging: If Lua scripts are in use, run script debug yes to enable debugging and identify potential infinite loops in scripts.
  7. Config Check: Execute config get '*' to review current configuration settings that might inadvertently cause loops, such as aggressive retry policies.
  8. Save and Restart: As a last resort, if the loop cannot be identified or stopped and is causing service degradation, save the current state using bgsave (if possible) and restart the Redis server using shutdown save.
