I found the issue. In addition to the AWS client I also start 
other applications which might
become zombie processes. For these processes I added this coding:

signal(SIGCHLD, &handleSigChld);

extern (C) void handleSigChld(int sig) nothrow @nogc @system
     {

         import core.sys.posix.sys.wait : waitpid, WNOHANG;

         int status;
         waitpid(-1, &status, WNOHANG);
     }

But this coding has a bad influence on the AWS client causing 
spurious exceptions.

Kind regards
