We use the library org.apache.http.client.HttpClient in accessing other web services from our web services. 

HttpRequestBase requestBase = <set uri>
httpClient.execute(requestBase);

Now at certain times, this exception happens:

*

Sometimes this this one shows up

It seems like the http request is being aborted from the client-side. Are you using any sort of thread pool executors in your code, that are submitting requests, and are being cancelled later for any reason (maybe slowness in response from thrid party )?
