fork(): Resource temporarily unavailable
-
Hallo,
in einem C++ Programm tritte bei Benutzung von fork() der Fehler "Resource temporarily unavailable" den ich über perror abfrage auf, obwohl ich früher Prozesse damit starten konnte. Das sieht zunächst aus als, ob die gestarteten Prozesse nicht beendet werden, aber ps -ef lässt nicht darauf schliessen:

Auch nach langer Suche im Web habe ich keine Lösung gefunden. Habt ihr eine Idee?Viele Grüße

Es wäre sehr hilfreich, wenn du nützliche Informationen liefern würdest (zum Beispiel ein kleines, aber vollständiges(!), Beispielprogramm, welches den Fehler zeigt), anstatt Helfer mit seitenweise Informationsmüll von zweifelhaftem Belang zu vergraulen.
