The VM has 4GM memory and average utilization about 40%, but application team got "out of memory" error

Hi All,

We have 1 VM server has 4GB memory and application team requested to increase to 32GB because they keep receiving "Out of memory" error. The average utilization is less than 40% and peak utilization about 60% - 70%. Their application needs continuous memory segment.

For me, I don't think we need to add memory, has anyone had similar experience? We need to add memory or they can optimize their application?

Thanks!
