fd-leak-diagnosis

Diagnose file descriptor leaks by running an automated multi-layer analysis that drills down from system-wide FD limits to specific process-level leaks, classifies FD types, and identifies the root cause of CLOSE_WAIT accumulation.

Too many open files errors occur because a file descriptor leak exists, which this skill pinpoints by dynamically selecting specialized diagnostic scripts to trace whether the issue is a socket leak, epoll instance leak, or an unclosed file handle.

Troubleshoot epoll instance leaks and inotify watch limits using an evidence-based diagnostic path that automatically branches into specialized analysis based on initial baseline findings of FD usage.

You need lsof and strace because this skill depends on them, alongside bash and ss, to execute its multi-layer diagnostic scripts and perform automated root cause analysis for FD leaks in Linux environments.

You can identify an unclosed file handle in a logging module using this skill's code-level root cause identification, which automatically drills down from process-level FD classification to pinpoint the exact leak source.
