Tomcat mögliche memory leak

Der Universität, wo ich arbeite, verwendet einen Tomcat/Railo-server zum Rendern von ColdFusion-Seiten. Für etwa 6 Monate (vorher war ich angestellt) die Server wurden nach dem Zufallsprinzip Absturz zu unterschiedlichen Zeiten, in der Regel runnign service railo_ctl restart hat Feste hte Problem, aber in letzter Zeit hat dies nicht so gut funktioniert.

In den letzten zwei Wochen habe ich verengt das Thema auf, und ich bin mir ziemlich sicher, Tomcat, wo das Problem herkommt. Ich habe noch nie verwendet, Tomcat, also ich bin mir nicht sicher, wo zu beginnen. Ich haben überprüft, dass die Catalina.Dateien aus, und schaute auf die Zeit, wenn der Server abgestürzt und fand diese Fehlermeldung:

SEVERE: The web application [] is still processing a request that has yet to finish. This is very likely to create a memory leak. You can control the time allowed for requests to finish by using the unloadDelay attribute of the standard Context implementation.

Dieser SCHWEREN Fehler druckt einen vermutlich 200 mal

Mir ist auch aufgefallen, dass dieser Fehler kam, aber es scheint nicht zu pop-up in der gleichen Zeit der Server abgestürzt

Irgendwelche Gedanken oder Vorschläge zu diesem würde sehr geschätzt werden.

Dieses Problem ist wahrscheinlich besser geeignet für die ServerFault Exchange. Möchten Sie vielleicht, um post dort auch.
Vielen Dank, ich habe diese Frage auch dort.
welche Versionen von Tomcat/Railo/JRE sind Sie? vielleicht ein einfaches upgrade helfen könnte?
Railo : Railo 3.3.4.003 final Java : 1.7.0_25 (Oracle Corporation) 64bit Tomcat: Apache Tomcat/7.0.22
Ich schließe die SF-version von dieser Frage, da ich denke, dass die Frage Sinn macht, dann hier.

Ich glaube, das ist die Wurzel des Problems:

SCHWERER: Die web-Anwendung [] ist noch der Bearbeitung einer Anfrage,
noch nicht fertig

Etwas in Ihrem app verursacht einen thread zu hängen, und wahrscheinlich sterben. Leider sind diese Arten von Fehlern sind extrem schwer zu diagnostizieren. Was ich tun würde, wenn ich du wäre, ist die überwachung der app mit so etwas wie FusionReactor, und beobachten Sie insbesondere für lang laufende Anfragen in Ihrer app. Dies könnte Hinweise darauf geben, was Stück Ihrer app verursacht diese Probleme.

Ich würde installieren FusionReactor in eine separate Instanz von Tomcat so dass es überwachen Sie Ihre app bis zu und nach dem es ist der Tod. Wieder, dies könnte mehr Aufschluss darüber, welche genauen threads hängen und/oder sterben.

FusionReactor ist ein kommerzielles Produkt, sondern kommt mit einer 30-Tage-Testversion, in der ist es voll funktionsfähig. Wenn Sie gehen, um die Verwaltung dieser Anwendung, eine Lizenz wird wohl wieder lohnt, aber wenn Sie können nicht schwingen, dann gibt es andere JVM-monitoring-Produkte wie VisualVM und dergleichen. Sie sind nicht so gezielt wie FusionReactor, aber Sie könnten in der Lage sein zu helfen.

Wiederum auf den JVM-Speicher Protokollierung als hier dokumentiert. Dann füttern Sie diese Protokolle zu GCViewer

Sollte Ihnen ziemlich guten Einblick in die Verwendung des Speichers. Sie werden sehen, ein Sägezahn-Muster der Speichernutzung, aber es ist, wie tief der Boden des Sägezahn-Muster geht jedes mal sagt Sie, wenn Sie ein Leck. wenn die Mulden des Sägezahn marschieren nach oben, das ist ein Zeichen.

Können Sie auch verwenden, kill -3 auf den Prozess, Sie zu erzählen, um es dump der aktuellen threads zu seiner log-Datei. Wenn du das 5 Sekunden auseinander, 5-mal, können Sie öffnen Sie die Protokolle in Samurai

Du suchst threads, der Stapel sieht, die gleiche oder ähnliche in jeder der aufeinanderfolgenden dump. Sie werden die stuck lieben. Was ist die CPU-Last, wie auf den Prozess, wenn es abstürzt?
