Summary

Claude Code v2.1.81 was running five instances at the time of shutdown. A force shutdown was initiated at 01:36:33, with 162 processes still active, including 21 Python processes, before the system booted at 01:37:11.

Key Takeaways

The shutdown process revealed 162 running processes, including 21 Python instances, indicating a potential issue with process management.
Orphaned Python processes were identified, all stemming from a command that executed base64-decoded code, but no malware was detected.
The incident was likely caused by a runaway spawning loop from a Claude Code tool or a subprocess bug in a script.
Recommendations include checking for looping agents and setting a process limit to prevent future issues.
