Je cours une application sur GAE/J et obtenant une MemcacheServiceException. Je n'utilise jamais explicitement Memcache, donc je suppose que cela a quelque chose à voir avec appstats ou un service caché que je ne comprends pas bien - mais je suis frustré de ne pas pouvoir dire où le problème se passe. Aucune partie de la trace de la pile n'est dans mon code.Des idées sur l'origine de cette exception?
Comme les demandes ne prennent que 2 secondes pour échouer (20 cpu secondes!) Je ne pense pas que je rencontre un problème de délai.
est en dessous du message d'erreur complet:
