OS                         Sun Solaris Sparc 2.Application Server   jboss-4.2.3.GA 3.java                        Oracle JRockit(R) version "1.6.0_05" 4.Ext. Lib.                   Apache http Client ( http://hc.apache.org/httpclient-3.x/ http://hc.apache.org/httpclient-3.x/) I have one stateless session bean which sends SMS Message to mobile using http client. my session bean looks like : @Stateless @Remote(CommonFasade.class) public class CommonFasadeBean implements CommonFasade {     private HttpClient httpClient = null;     public HttpClient getHttpClient() {         if (httpClient == null) {             SimpleHttpConnectionManager manager = new SimpleHttpConnectionManager();             manager.getParams().setConnectionTimeout(5000);             manager.getParams().setSoTimeout(5000);             httpClient = new HttpClient(manager);         }         return httpClient;     }     public void sendSMS(String fullSms, String phone, String from) {         HttpClient httpClient = getHttpClient();         phone = Utils.trimPhone(phone);         phone = getPhone(phone);         if (phone == null) {             return;         }         String sendToPhone = null;         switch (phone.length()) {         case 8:             sendToPhone = "%s2B995" + phone;             break;         case 9:             sendToPhone = "%s2B995" + phone.substring(1);             break;         default:             return;         }         String url = " http://192.168.19.194:13013/cgi-bin/sendsms?from= http://192.168.19.194:13013/cgi-bin/sendsms?from=" + from                 + "&username=1&password=1&to=" + sendToPhone + "&text=%s";         long sc = -999;         try {             for (String sms : prepareSmsList(fullSms)) {                 GetMethod method = new GetMethod(String.format(url, "%", sms));                 try {                     sc = httpClient.executeMethod(method);                     if (sc == HttpStatus.SC_ACCEPTED) {                         String response = method.getResponseBodyAsString();                         if (response.toLowerCase().indexOf("sent") != -1) {                             logSMS(sms, phone, from);                         }                     }                 } finally {                     method.releaseConnection();                 }             }         } catch (Exception e) {             e.printStackTrace();         }     } this code worked for tree years, but problem appeard some days ago. every second or third day my jboss application server crashes. when i trying to find promlem i found this : 1. into solaris : "netstat -an|grep 192.168.19.194|wc -l  (this is SMS sender HTTP server)"      and result was : 12678 this is client socket connections from my jboss as, all of them is on a CLOSE_WAIT state. After this when i looking into the jmx-console i found this : http://community.jboss.org/servlet/JiveServlet/showImage/2469/MBeanView.jpeg http://community.jboss.org/servlet/JiveServlet/downloadImage/2469/450-264... My question is why i have 12826 stateless session bean isntances into as ? Into my jboss as stateless session pool config max size is 30. i think that something changed into  HTTP Server or into network. but i need workarount of this porblem . is this pattern right for using http clients ? Maybe it will be more correct to use MDB for this ? when current size of my stateless session bean achieve 40000 the jboss as going down. can anybody help me what should i do ??? ___________________ Regards, Paata Lominadze. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/535357#535357] Start a new discussion in EJB 3.0 at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
