[jira] Created: (HTTPCORE-237) Getting very frequent
SocketTimeOutException
Getting very frequent SocketTimeOutException
--------------------------------------------
Key: HTTPCORE-237
URL: https://issues.apache.org/jira/browse/HTTPCORE-237
Project: HttpComponents HttpCore
Issue Type: Bug
Components: HttpCore
Affects Versions: 4.0.1, 4.0.2
Environment: PROD
Reporter: Simona Afifi
We are using ThreadSafeClientConnManager and we close the stream at the finally block and yet we see very frequent occurences of this exception:
java.net.SocketTimeoutException: Read timed out
at java.net.SocketInputStream.socketRead0(Native Method)

Sample code:
HttpClientWrapper.class
public HttpResponse execute(HttpPost httpPost, int timeout) throws IOException {
HttpClient httpClient = new DefaultHttpClient(connManager, initParams(timeout));
httpClient.getConnectionManager().closeExpiredConnections();
return httpClient.execute(httpPost);
}
Service.class
-------------------
private String invokeHttpGet(HttpGet httpGet) throws Exception {
String responseStr="";
HttpEntity entity= null;
try{
HttpResponse response = httpClientWrapper.execute(httpGet);
entity = response.getEntity();
if (entity != null) {
responseStr = EntityUtils.toString(entity);
}
}catch(Exception e){
if(httpGet!=null)
httpGet.abort();
throw e;
}finally{
if(entity!=null) entity.consumeContent();
}
return responseStr;
}

[jira] Resolved: (HTTPCORE-237) Getting very frequent
SocketTimeOutException
Posted by "Oleg Kalnichevski (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HTTPCORE-237?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Oleg Kalnichevski resolved HTTPCORE-237.
----------------------------------------
Resolution: Invalid
Simona
This is because the socket timeout value set by your application must be too aggressive (too low). This is most certainly not a bug in HttpCore. Try increasing the socket timeout.
