Incomplete response received from application
проблема и в самом деле была в том, что не хватало памяти (а не ошибка приложения, как предполагалось ранее). Приложение хостилось на VDS c OpenVZ со swap = 0 kb и без возможности перенастроить контейнер c vswap отличным от нуля. Решение в двух вариантах: - переезд на VDS с KVM (и с последующей настройкой vswap) - переезд на машину, у которой показатель занятой оперативы не превышает 80%
