幾個同時發出HTTP請求後Web應用程序被破壞

Question

在Tomcat上運行的基於Spring的Web服務的約10-15個同時請求關閉Web應用程序之後。 請建議基於以下錯誤日誌中的解決方案：

Answer 1

從我從上面的日誌中看到，事情是發送終止信號到Tomcat。 檢查可能影響tomcat的後臺運行的服務。 TOMCAT_HOME/bin有catalina.sh/catalina.bat。運行這些會導致tomcat關閉。

[INFO: A valid shutdown command was received via the shutdown port.Stopping the Server instance.**] 

以上聲明證明了這一點。
