Maximum requests per seconde on elasticsearch node

I installed elasticseach on a linux server, I have a single node of it. I have a csv file of several tens of thousands of lines which contains IDs, the goal is to iterate over this file and retrieve the data from the elasticsearch index. The problem is that after a few thousand requests, elasticsearch crashes. Please how much is the number of requests per second for a neod elasticsearch? Thanks

It is impossible to tell as it depends on the data, data volume, queries, configuration and available resources. If you provide more details about hardware used, cluster configuration and what exactly you are doing someone may be able to provide some feedback.

How many GB of memory is allocated? How do you send data? By Kibana upload, FB or LS?
Any trace in logs? Which version do you use?
