IBM Websphere auf Windows - OutOfMemoryError: Fehler beim erstellen eines thread

Ich habe eine J2EE-Anwendung läuft auf einem IBM Websphere Application Server auf einem Windows-Betriebssystem.

Gelegentlich sehe ich einen OutOfMemoryError-Exception mit der folgenden information in den javacore-Datei.

1TISIGINFO     Dump Event "systhrow" (00040000) Detail "java/lang/OutOfMemoryError":"Failed to create a thread: retVal -1073741830, errno 12" received 

Java ausgeführt wird, mit den folgenden Konfigurationen:
-Xms512m
-Xmx1350m
-Xscmx50M

Analyse der javacore Datei, die Anzahl der threads, die sind nur 124.
Die Analyse der heap-dump, der belegte Speicher vom heap ist über 500Mb.

Angesichts der relativ normale Anzahl von threads und heap-Größe, viel niedriger als die maximale, ich bin versucht, herauszufinden, warum ich diese Fehlermeldung sehen?

Ich bin nicht sicher, ob das hilft, aber hier ist der Obere Bereich der javacore Datei...
