Je demande des informations sur le Web à l'aide de services Web renvoyant XML. Cela fonctionne très bien tant que l'appareil n'est pas verrouillé. Si l'utilisateur éteint l'appareil ou s'il se verrouille après le délai d'attente configuré, le service Web échoue. J'ai ajouté le stacktrace ici. Ce que je me demande: Je ne fais rien dans mon application de test avec le résultat du webservice (appelé via SOAP). Encore il se bloque, en essayant d'appeler "mprotect" ou quelque chose. Quel est le problème et comment puis-je continuer à utiliser mon application si l'appareil est verrouillé? J'ai toujours pensé que le verrouillage est différent de la mise en arrière-plan - l'application doit rester active.Exception lorsque webservice est appelé après que le périphérique a été verrouillé
J'ai découvert que "errno 12" signifie "mémoire insuffisante" mais ce n'est pas vrai. Si l'appareil ne se verrouille pas, l'application de test dure plusieurs heures. Dès qu'il se verrouille, il fait une requête de plus et se bloque. Aussi Instruments montre une utilisation de la mémoire constante de 40Mo (comme dans la question de Luc: Explanation of MProtect Errno 12 (ENOMEM))
Mprotect failed at 0x5f55000 (length 1396736) with errno 12

Quelle version de MonoTouch + Xcode vous utilisez? J'ai les quelques jours à venir au travail mis de côté pour vraiment s'attaquer à ce problème! – Luke
J'utilisais MT 4.0.1, Xcode 3, SDK 4.3. Si vous trouvez une solution, s'il vous plaît faites le moi savoir. Mais comme c'est un MT interne je n'ai pas trop d'espoir. – Krumelur
Une autre question a surgi - http://stackoverflow.com/questions/5819700/why-is-our-monotouch-app-breaking-in-the-garbage-collector-it-is-not-out-of-memo Il semble vraiment allumé et prêt à passer un test de travail alors j'espère qu'il y a une lumière au bout du tunnel! – Luke
