Spring Boot Sock Js ограничение веб-сокетов

0 голосов
/ 30 апреля 2020

У меня есть приложение с загрузочной пружиной, которое использует Sock Js для связи с веб-страницей AngularJs, и мне нужно, чтобы мое приложение поддерживало соединения 1k (webscokets).

После некоторого нагрузочного тестирования я увидел, что после соединения ~ 256 сервер больше не создает новые соединения webSockets.

Я получаю следующие ошибки: 

java.lang.NullPointerException

Я также попробовал это на веб-службе Azure и получаю следующее:

Я попытался обновить конфигурацию Tomcat, но никаких улучшений не было.

Что я должен сделать, чтобы мое серверное приложение могло поддерживать несколько подключений вебскокетов?
