Hi Champs,

Today I am sharing a case study for Excessive usages of threads on session expiration processing in Sitecore 9.2 XP and Sitecore 9.2 XC deployments.

Root cause for the issue:

Due to an issue in Session State providers during high load situations, Sitecore instance may end up in a thread starvation issue which can cause the website to become unresponsive.

Solution to the issue:

Sitecore has provided  SC Hotfix 367157-1.zip hotfix which is recommended to apply to all Sitecore 9.2 XP and Sitecore 9.2 XC deployments.

The patch should be installed on CD instances (or on servers that are dedicated for handling session expiration, if those are a part of a custom setup).

Happy Learning
