I need a little bit of help understanding this cryptic issue. While indexing data, it fails and throws this error. I have checked my elasticsearch's health but it shows me that it's running, and it's health is green. I have checked the elasticsearch logs as well, and occasionally see an OutOfMemory exception thrown for some of the slow operations, could this be the cause of the EngineClosedException? Shouldn't there be some indicator like the health goes red if some engine is closed?
