How to Troubleshoot Linux Servers With Unexpected Swap Usage

11/10/2026

Swap usage may persist after memory pressure passes, or indicate workloads that exceed available RAM.

Checks to make

Review memory pressure, process resident sets, kernel logs, and application behavior over time. Distinguish allocated swap from active swapping, inspect major page faults and I/O, and avoid changing swappiness before identifying demand.

When to get help

Linux administration can diagnose memory pressure and capacity needs. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
