Spring Boot uygulaması tüm CPU'ları kullanmaya başlar

Temel bir Spring Boot (1.3.2.RELEASE) uygulamasına sahibim. Bu uygulamayı IntelliJ IDEA'dan bağımsız bir uygulama olarak çalıştırıyorum (SpringApplication.run(...)).Spring Boot uygulaması tüm CPU'ları kullanmaya başlar

Uygulamayı bir süre çalıştıktan sonra, java işleminin tüm kullanılabilir CPU'ları kullanmaya başladığını birçok kez fark ettim. Aslında bunun aslında Bahar süreci olduğunu doğruladım ve örneğin IDEA değil. Bu, geliştirme makinemde gerçekleşirken, onunla herhangi bir etkileşim yapıyorum.

jstack Kullanarak aralarında bir dakika bulunan 3 farklı yığınlama işlemi gerçekleştirdim. Bu stacktraces arasında farklı olan iplikleri aşağıda listelenmektedir:

Bulabildiğim tek ilgili kaynak eski bir hata raporu: https://bz.apache.org/bugzilla/show_bug.cgi?id=45661

Bu hatayı nasıl çözeceğiniz veya izleyeceğiniz konusunda herhangi bir öneriniz var mı?

[Bu soru] 'nun bazı yanıtları (http://stackoverflow.com/questions/755899/monitor-cpu-usage-per-thread-in-java) kullanımda olabilir –

Çok benzer bir sorunum var Tomcat 8.0 ile. Bir VMWare ESXi 5.1 sunucusunda dağıtılan bir Windows 2008 R2 üzerinde Java 1.8.0_77 kullanarak Tomcat 8.0.33 çalıştırıyorum. Çevreniz benzer mi? Herhangi bir geçici çözüm buldunuz mu? –

Çevremim daha basit: bir win7x64 kuruluşu. Bu kendi geliştirme makinemle ilgili. Henüz bir çözüm bulamadım, ancak ilgili bir bağlantı https://youtrack.jetbrains.com/issue/IDEA-153821 (IntelliJ IDEA'da sorundan gerçekten hata ayıklama yapmamı engelleyen bir sorun). – DieterDP

Protokolleri Tomcat konektörlerindeki yerine NIO.2 yerine NIO.2 kullanarak zorlamayı deneyin.

Değiştir server.xml bu şekilde:

<Connector port="8080" 
    protocol="org.apache.coyote.http11.Http11Nio2Protocol" 
    connectionTimeout="20000" 
    redirectPort="8443" /> 
<Connector port="8009" 
    protocol="org.apache.coyote.ajp.AjpNio2Protocol" 
    redirectPort="8443" />

bağlamda NIO kullanırken bazı Java hata var gibi görünüyor.
