one task missing during the execution

one task missing during the execution

[compguy45]

I have 6 tasks......There properly wait at the first entry and print out their ids....then they all accounted for inside doSomething but right before doSomethingElse id 123 just disappears...i have filled my code with output statements and during the execution its showing on screen that its there but right begotr doSomethingElse its gone....Should it not wait like all the others at the second entry?? Can someone suggest how to debug this and find whats going on.....Output to my screen is below..


        123
        132
        213
        231
        321
        312
Inside doSomething by id......... 312
 
Inside doSomething by id......... 132
  
Inside doSomething by id......... 231
  
Inside doSomething by id......... 213
  
Right before doSomethingElse  312
Inside doSomething by id......... 123
  
Right before doSomethingElse 132
Inside doSomething by id......... 321

What, exactly, were you expecting us to do?  Figure out what your entire program looks like just by seeing the output, so that we could help you debug it?  Sorry, but I don't think anyone on this group has that kind of mind-reading ability.

i didn't expect someone to debug the code but i figured just by looking at output since all tasks have same body someone with more experience can suggest what to look for...

i am so sorry about that

It would be _so_ much easier to actually _have_ a body to look at.
Just as Adam says: we are not mind-readers...

Do be sorry - post the task body/program instead

Have you included an exception handler at the end of each of your tasks?
All tasks (but the main task) terminate silently in case of an
exception, so it can be useful to have a final exception handler in any
task for registering that it has been terminated by an exception.

Sieve of Eratosthenes?  I'm also guessing that your missing task is 
raising an exception.

I added...

with Ada.Exceptions;  use Ada.Exceptions;
with Ada.Text_IO;     use Ada.Text_IO;

  exception
 when tasking_error =>
            Put_Line ("Something is wrong here" & Exception_Information (Error));
 when others =>
               put("some other error occurred");

I get error xpected private type "Ada.Exceptions.Exception_Occurrence"
 found type "Ada.Strings.Truncation"
" compilation error

when i just say when tasking_error => "Some error" get compiles fine and prints "some error" which tells me there is tasking error....

is there way to get more information about error?

when Error : tasking_error =>
   Put_Line ("Something is wrong here" & Exception_Information (Error));

and

with GNAT.Exception_Traces;
...
begin
   GNAT.Exception_Traces.Trace_On (GNAT.Exception_Traces.Every_Raise);
