How to Find Why a Linux Server Is Running Out of File Descriptors

A process can exhaust its file descriptor limit through many open connections, leaked files, or an undersized limit.

Checks to make

Identify the process and current limits, inspect open descriptor types and growth over time, and check application connection cleanup. Compare service and system limits; raise them only after understanding the workload and monitoring the result.

When to get help

Linux administration can diagnose process limits and connection handling. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
