Hi, when i see top command virtual memory usage for ElasticSearch is high. I have allocated min 1G and max 2G heap size for it. How can i control the virtual memory usage? I am getting OOM frequently on ElasticSearch log.

If you get OOM, you should take a look at RSS (resident set size) of the process. The VIRT (virtual memory) can span GB or TB, it does not matter at all.
