Hi Sidath, histograms have a limited number of buckets, they should not grow indefinitely.
The reason for your OOM might be "cardinality explosion": Maybe you generate more and more different label values, each set of label values adds a new histogram. If this is not the case, and you see increasing memory usage with a fixed set of histograms, please open an issue on https://github.com/prometheus/client_java, ideally with a way to reproduce this.
