High Memory Utilization
We have an application hosted on a JVM, which has around 16 GB of memory allocated. With only 3-5 users logged in, we see that the memory usage at times is around 12-14 GB. We checked the clipboard size of the requestors and none of them is more than a few MB (100 MB maximum at times). Cache size is not considerable either (all caches included amount to less than 1 GB). Any idea what else could be causing this high memory usage?
Which version of Pega are you using?
Would also recommend analyzing heap dumps to check top suspects and histograms.

HI
For starter can you check if GC is happening or not?

Hi,
I would like also mention that will be nice to see the all JVM parameters which are you using to run this process.
Thanks,

Hi,
Take a heap dump and analyze the Top contributors & Objects. heap dump will be in binary format, you can use MAT(Memory Analyser Tool) to decode.
