java run out of memory Problem

Habe ich eine jar-Datei ausgeführt, die auf einer amazon-ec2-m1.large instance mit linux 64-bit Betriebssystem.
I run out of memory nach verschiedenen Stunden, in der Regel zwischen 2-4, obwohl in meinem letzten Protokoll schreiben (bevor der Fehler Datei erstellt ) sehe ich Folgendes:

Memory - 
     totalHeapSize: 264 MB, 
     maxHeapSize: 1656 MB, 
     freeHeapSize: 220 MB

Wenn ich einen Blick aus dem jar gestartet, bis in run out of memory - alle Werte sind die gleichen und die freeHeapSize ist zwischen 200-230 MB (ich check alle 30 Sekunden und das System.gc() )

in der hs_err_pid2250.melden Sie wrriten:

    #
    # There is insufficient memory for the Java Runtime Environment to continue.
    # Cannot create GC thread. Out of system resources.
    # Possible reasons:
    #   The system is out of physical RAM or swap space
    #   In 32 bit mode, the process size limit was hit
    # Possible solutions:
    #   Reduce memory load on the system
    #   Increase physical memory or swap space
    #   Check if swap backing store is full
    #   Use 64 bit Java on a 64 bit OS
    #   Decrease Java heap size (-Xmx/-Xms)
    #   Decrease number of Java threads
    #   Decrease Java thread stack sizes (-Xss)
    #   Set larger code cache with -XX:ReservedCodeCacheSize=
    # This output file may be truncated or incomplete.

Außerdem benutze ich threadpoolexecutor mit 30 core threads und 100 max (Benutzer nie mehr als 30, obwohl einige Male ich die ganze 30)

Endlich habe ich den Benutzer bonecp connection pool mit 50 verbindungen

Irgendwelche Vorschläge?
🙂

Nach Anregung, ich habe ein heap-dump nachdem Sie die Anwendung ausführen, von meinem lokalen pc.
Wie kann ich weiterhin hier?
Sind die kritischen orange Sprünge wichtig?, oder einfach nur die verwendet wichtig?
java run out of memory Problem

  • Vorschlag: erstellen Sie eine heap-dump und herauszufinden, was die Ursache dieser. Hier nicht sichtbar.
  • Es sieht aus wie die JVM crashed beim Start, als bezeugt durch die Tatsache, dass der Absturz kommt aus versuchen, erstellen Sie einen thread für die GC, das fehlen von Anwendungs-threads, und VM state:not at safepoint (not fully initialized). Wird die Anwendung gestartet, Kopien von sich selbst trennt in JVMs?
  • Wie Sie eine virtuelle Maschine auf einem gemeinsam genutzten Rechner, ist es möglich, die eigentliche Maschine ist der Speicher ausgeht?
  • joni - Nein, peter ist - Nein
