Hi Arturo,
It seems like you are ending up with partially closed connection. This could be caused by a number of things:
1) the large wait between method executions
2) an older version of JSSE. JSSE in pre 1.4 JVMs has been known to be pretty flaky.
3) the server or proxy server is under high load and simply drops the connection.
I would suggest trying one or both of the following:
1) Disable connection reuse by setting the "connection: close" header and/or using HTTP 1.0:
Method.setRequestHeader("Connection", "close");
or
Method.setHttp11(false);2) Catching the recoverable exception and executing the method again.

thanks Mike,
I´M USIGN A PROXY, WEBLOGIC SERVER 6.1, RUNNING THE PROCESS FROM UNIX AND THIS IS AN EXAMPLE OF MY CODE:
(NOTE: this code runs every 1 minute from a threed.sleep)
url="http://www.whatever.com";;
HttpClient client = new HttpClient();
client.getState().setProxyCredentials(null, null, new UsernamePasswordCredentials(System.getProperty("http.proxyUserName"), System.getProperty("http.proxyPassword")));
client.getHostConfiguration().setProxy(System.getProperty("http.proxyH ost"),Integer.parseInt(System.getProperty("http.proxyPort","80")));
GetMethod method1 = new GetMethod(url);
try{
statusCode = client.executeMethod(method1);
System.out.println("Return Code=> " + statusCode);
}catch (HttpRecoverableException e) {
System.out.println("An recoverable exception occurred,retrying. " + e.getMessage());
e.printStackTrace();
}finally{
System.out.println("Releasing Connection method 1....." );
method1.releaseConnection();
}
THIS IS WHAT THE LOGGING IS DISPLAYING:
(NOTE: i don´t always get this error, most of the time the code works fine, but when i get the error and since is a runnable process, i need to stop the process by killing its id process, stop the weblogic server, wait like 30 minutes, and then try again)

Hello Arturo,
This problem could be caused by a number of things. Please post a wire
log <http://jakarta.apache.org/commons/httpclient/logging.html> and
some sample code and we should be able to get to the bottom of the
problem.
