Unknown
Root Cause
A defect or configuration issue in the operating environment.
Resolution
Here’s the explanation for the reported behavior:
When the project has a growth in the amount of requests through a particular service, the Requestor pool size must be adjusted to accommodate the growth.
The Adjust and Monitor approach is used to increase the Requestor pools in small steps (for example, 20-30-40 requestors). Post this, the growth of concurrent requestors and its impact on the Heap Utilization is monitored.
