JBoss eventually stops responding to request, but no OOME


JBoss eventually stops responding to request, but no OOME

Hope that helps It sounds like your jboss server is running out of threads to allocate and is waiting for a new one to become available. Try triggering a thread dump (ctrl-\) and see if you find any threads suspiciously locked and waiting in some of your code. Quite possibly you have a deadlock or memory leak somewhere in your code which is causing old threads to lock up and never be released.
Alternatively try what the guy you linked to did, i.e. increasing the amount of threads available.

To fix the issue you can do The problem is interrupting fadeIn or fadeOut prematurely. When you do this, the item gets a new "baseline" opacity. fadeIn does not fade to an opacity of 1, it fades to the baseline (for example, if your element has an opacity of .8 originally, and you hide it, fadeIn will fade to .8 not 1).
To fix this issue, use fadeTo with an opacity of 1 instead of fadeIn.

fixed the issue. Will look into that further You're almost there! After receiving one request, you need to start listening for another one.
code :
private void OnRequestReceive(IAsyncResult result) 
{ 
    HttpListener listener = (HttpListener)result.AsyncState; 

    HttpListenerContext context = listener.EndGetContext(result); 
    HttpListenerResponse response = context.Response; 
    byte[] buff = {1,2,3}; 

    response.Close(buff, true); 

    // ---> start listening for another request
    listener.BeginGetContext(new AsyncCallback(OnRequestReceive), listener); 
}

will be helpful for those in need Occasionally, after I deploy a war to my standalone/deployments folder, JBoss starts as usual, deploy the app without any error and.... BLANK PAGE. , That issue was fixed in JBoss 8 (Wildfly). We'll never know :)
When a request to a proxy times out, what happens if/when the destination server eventually gets around to responding?

When a request to a proxy times out, what happens if/when the destination server eventually gets around to responding?

seems to work fine It's implementation-dependent, but any proxy that conforms to RFC 2616 section 8.1.2.1 should include Connection: close on the 504 and close the connection back to the client so it can no longer be associated with anything coming back from the defunct server connection, which should also be closed. Under load there is the potential for race conditions in this scenario so you could be looking at a bug in your proxy.
If the client then wants to make further requests it'll create a new connection to the proxy which will result in a new connection to the backend.

With these it helps Here is an approach for you:
I added some comments in order to make it readable.
code :
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class Assignment4 {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);//Creating the scanner

        int number = 0;
        //List to save all the numbers you write
        List<Integer> numbers = new ArrayList<>();

        System.out.println("Enter a positive integer. Enter '-1' to quit.");//Asking the user to input a number
        //This loop going to repeat until met the condition
        while(number != -1) {
            number = scan.nextInt();//Scanning for the number


            if(number>0){
                boolean prime = true;
                for(int j = 2; j <= number/2; ++j)
                {
                    if(number % j == 0)//To see if the number is prime
                        {
                            prime = false;
                            break;
                        }
                 }
                 if (prime)//If its a prime number
                     System.out.println(number + " is a prime number.");
                 else//If it is not a prime number
                     System.out.println(number + " is not a prime number.");
               //We save the number
               numbers.add(number);
            }
        }
        System.out.println("Your numbers were");
        numbers.forEach(System.out::println);


    }
}
Enter a positive integer. Enter '-1' to quit.

3 is a prime number.

5 is a prime number.

7 is a prime number.
8
8 is not a prime number.
31
31 is a prime number.
33
33 is not a prime number.
-1
-1 is a prime number.
Your numbers were
