I am using Spring RestTemplate to make a HTTP Calls to my RestService. I am

Now machine which is running my code (which uses RestTemplate) to make call
to my RestService, I see lot of TIME_WAIT connections opened on that
particular machine?
- Is there any reason why it happens with RestTemplate or the way I am
using it?
- Also, what is the connection between TIME_WAIT and HTTP Client calls to
my RestService? I am not able to understand this as well. Does HTTP Calls
has any significance on TIME_WAIT? There might be some theoretical
explanation for this I guess.

And here is netstat details on my box which is running my code to make HTTP
Calls to my RestService. I am always seeing very high number of TIME_WAIT
connections.
72 ESTABLISHED
2 FIN_WAIT1
17 LISTEN
3405 TIME_WAIT
This is rather a TCP issue. As far as I can see, Spring Web 3.1.x uses
version 4.1 of HttpClient [1] and this one is unsupported. I do not know
wether 4.4 is ABI compatible with 4.1 but you should update the
HttpClient in your POM and retry, maybe your problem will go away.
I have found a quite good explanation about the issue you are
experiencing [2], [3], it might be worth to discuss this with your admins.
