Average Memory Utilization is 90%

Hi PI gurus,

Average Memory Utilization is 90% ,

Please note below:

1. synchronous message message count daily is approx 60000

2. Memory is 36 GB - In use -32.8 GB and Available 3.2 GB

3.CPU average utilization is 3%

We are worried that Memory utilization can go high , which can cause issues.

Please help us and let us know if we need to increase to RAM or there is some other issue for such high memory utilization?

Regards,SV
