[AWI] Increased CPU and Network Usage During SAML-Based Sessions

Issue/Introduction

Following an upgrade to v24.4.x users have reported a gradual rise in CPU consumption and network activity within AWI environments. These performance indicators reset when the AWI service is restarted, suggesting the load builds up over time during regular operation.

This behavior is most consistently seen during SAML-based authentication flows. When a SAML user logs in, AWI initiates two connections to the Automation Engine, while only one connection is released upon logout. The additional connection remains active and continues to accumulate with repeated logins. As these connections build up, overall network throughput increases and CPU demand rises, particularly as the system performs more frequent garbage collection cycles.

This pattern is not observed when using standard AE authentication.
