System.OutOfMemoryException - Nest Elasticsearch

Elastic Stack Elasticsearch
1

Off Late I've been facing the below issue a lot(sometimes even while indexing a large document it has this problem). Can some one tell me what can be the reason behind this?

I just tried to run a simple search application which will return a 5 documents sorted in descending order of indexed date.

var response = client.Search<Document>(s => s
                                   .Size(5)
                                   .Sort(so => so
                                   .Descending(d => d
                                   .IndexedDate)));

The same code works perfectly fine when I run on the local host. Dont know whats wrong if I run the application on the server.

FailureReason: Unexpected when trying to POST http://192.168.x.y:9200/codetweaks54/document/_search

Again. This is not related to elasticsearch code IMO.

You should move your question to #development channel I think.

Unless you see in elasticsearch nodes a trace?

Yeah. I remember posting a similar question which as you said is not problem with ES after looking at my code. But this time its giving a problem only at few instances. like local server is perfectly fine while running it on a different server is throwing this. Thats why posted this question again.
Anyways will move it to development.

Thanks David.
