I'd first encourage upgrading both elasticsearch and the jvm.
Then install monitoring to understand more about what is happening.
Also tell us more about your machine, settings, indices, shards...

as now, i do not have a plan to upgrade jvm, because it's on product env.
i may try to upgrade elasticsearch.
i will keep on watch if there are any other exception
