У меня есть встроенный в apache-tomcat движок интеграции на основе верблюдов Apache, использующий общедоступный http-клиент для http-вызова внешних веб-сервисов.В большинстве случаев при получении успешного вызова, но редко или при первом вызове после перезапуска сервера возникает ошибка сброса подключения.
Это не связано с тайм-аутом сокета или тайм-аутом соединения, которое должно применяться всегда.Я включил ведение журнала уровня HTTP и трассировку, приведенную ниже.

Может ли кто-нибудь помочь мне выяснить, что на самом деле периодически вызывает проблема сброса соединения?
