Here, your loop is *inside* the rendezvous. It means that the caller
(main) will not proceed until the loop is over. You probably meant:
task body DbCheck is
begin
accept StartRun;
-- Main returns here
While ContinueRunning=true loop
delay 20.0;
WriteDbMessages;
end loop;
> end DbCheck;
Note that:
1) your code has this problem, but it is not exactly what you describe
2) your code has a syntax error ("end Ciclo" instead of "end StartRun").
Please always provide the *exact code* that shows the problem, to allow
us to be maximally helpful.
