APS holding on to as much memory as allocated to it

76 Views

Dear experts,

We are in the middle of performing some VST on our BO POC server and we notice that no matter how the load varied (in the high load range by chaging the number of concurrent users) the core APS (we have 3 APS instances, one of which is the core APS with DSL Bridge, Webi Monitoring, Visualization; 1 APS with LCM services; 1 APS edge with everything else remaining from the processes running under the APS) holds on to max memory allocated to it, be it 6 GB or 8 GB, once it passes a "high load" mark and reaches its allocated memory (given b -xmg8g parameter) it doesn't release it even after load is decreased, unless SIA is stopped and restarted.

So, my question is: why is that? and how to plan to compensate for it in order to be able to sustain high load in this scenario and still be able to provide acceptable end user experience?

Thanks in advance for your input!
