What does the Emergency Ulimit Mitigation skill do?

It provides a set of immediate commands to increase system-wide file descriptor limits and restart services that have crashed due to resource exhaustion.

Which services can this skill recover?

While pre-configured for Docker and Traefik, the skill provides patterns that can be used to restart any systemd-managed service or perform general container cleanup.

How can I check my current file descriptor usage with this skill?

The skill uses commands like lsof and reads from /proc/sys/fs/file-nr to provide a percentage-based view of current file descriptor consumption.

Does this skill provide a permanent fix for ulimit issues?

Yes, it includes commands for both instant relief and the deployment of persistent monitoring timers and cleanup scripts to ensure long-term stability.

Resolves service crashes by increasing file descriptor limits and managing system resource availability.

关于

This skill provides an automated emergency protocol for handling 'too many open files' errors and associated service outages. It allows Claude to quickly diagnose file descriptor exhaustion, apply immediate kernel-level fixes, restart critical services like Docker or Traefik, and deploy long-term monitoring and cleanup scripts to prevent recurrence. It is an essential utility for system administrators and DevOps engineers dealing with high-concurrency environments where resource limits are frequently hit.
