Привет! Я использую Apache HTTP Client 4.0 для загрузки некоторых файлов на сервер по протоколу HTTPS. Загруженное приложение работает круглосуточно. Сегодня вдруг это бросило это исключение -
java.net.SocketException: No buffer space available (maximum connections reached?): connect

Может кто-нибудь помочь мне? Я совершенно не понимаю, что происходит?
Это исходный код для загрузки файла -
public File call() throws Exception {
HttpClient httpclient = new DefaultHttpClient();
try{
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
/*
* Create POST REQUEST
*/
HttpPost httpPost = new HttpPost(this.URL);
/*
* Create MultipartRequestEntity
*/
MultipartEntity multipartEntity = new MultipartEntity( HttpMultipartMode.BROWSER_COMPATIBLE );
/*
* Add POST Parameters
*/
multipartEntity.addPart(parameters[0], this.fileBody);
multipartEntity.addPart(parameters[1], new StringBody(this.TYPE));
multipartEntity.addPart(parameters[2], new StringBody(this.MAAID));
/*
* Add this POST Method
*/
httpPost.setEntity(multipartEntity);
/*
* Upload the file
*/
HttpResponse response = httpclient.execute(httpPost);
int responseCode = response.getStatusLine().getStatusCode();
logger.info("Response Code of HTTP Connectivity ["+ responseCode + "], " +
"it means ["+ response.getStatusLine().getReasonPhrase()+"]");
/*
* Check the server Response
*/
HttpEntity entity = response.getEntity();
if(entity != null){
String status = EntityUtils.toString(entity);
logger.info("Status of file upload from Server >>"+ status+"<<");
entity.consumeContent();
if(status.equalsIgnoreCase("OK")){
return this.fileBody.getFile();
}
}else{
logger.error("Unable to retrieve status of file upload from server");
}
}catch(NoRouteToHostException e){
logger.error("Internet connection to ["+ this.URL + "] is not available", e);
}catch(SocketException e){
logger.error("Unable to connect to "+ this.URL, e);
}catch (Exception e) {
logger.error("Exception while uploading the file["+ this.fileBody.getFilename()+ "] on ["+ this.URL+"]", e);
}finally{
try{
httpclient.getConnectionManager().shutdown();
}catch(Exception e){
// Ignore this exception
}
}
return null;
