Hi,

We're using Elasticsearch 2.3.4 with NEST as SDK for our .Net Application.

I read in one of the forum topics that number of concurrent connections always peaks at 381. What does it actually mean ?

Can someone please clarify me, if there is any limit in creating concurrent connections(NEST client)? If yes, what is the maximum number of connections that be can created concurrently?

Regards,  
Sreeram
