## Symptoms

- * A large number of WSTLSD processes are observed on the Security Gateway. Each WSTLSD process consumes approximately 58 MB of RAM, resulting in high overall memory usage.

* The Security Gateway experiences temporary network disconnects and becomes unresponsive for several minutes (approximately 10 minutes), after which normal operation resumes.

* HTTPS Inspection is not enabled. Only Categorize HTTPS Websites (URL Filtering) is enabled.

## Cause

Even when HTTPS Inspection is disabled, enabling Categorize HTTPS Websites for URL Filtering creates WSTLSD processes.

In this scenario, an excessive number of WSTLSD instances are created, leading to significant memory consumption and temporary degradation of Security Gateway stability.
