Multiple thread contentions related to the RequestorLock occur. As a result, some requests (such as, reload section) take a lot of time to process.

Not Applicable

Root Cause

This behavior is as per Pega product design.


Here's the explanation for the reported behavior:

In the logs provided, only two or three threads are involved.

By design, the application processes HTTP requests from a particular user individually. Hence, when two requests are received in a short time, the second request must wait till the first request is processed.

However, there is no issue if the contention lasts for a few milliseconds.
