This is almost impossible to answer without knowing more information. The only information that can be extracted from this snippet is, that the heap was too small. However without knowing how big the heap is, what kind of workload, and indexes the cluster has, it's next to impossible to get any help. Also the Elasticsearch version in use would help a lot. Just adding some more context will help people to take a closer look. ---
