J'ai une application J2EE s'exécutant sur un IBM Websphere Application Server sur un système d'exploitation Windows.IBM Websphere sur Windows - OutOfMemoryError: impossible de créer un thread
Parfois, je vois une exception OutOfMemoryError avec les informations suivantes dans le fichier javacore.
1TISIGINFO Dump Event "systhrow" (00040000) Detail "java/lang/OutOfMemoryError":"Failed to create a thread: retVal -1073741830, errno 12" received
Java est exécuté avec les configurations suivantes: -Xms512m -Xmx1350m -Xscmx50M
Analyse le fichier javacore, le nombre de threads ne sont que 124. Analyser la décharge du tas, la mémoire occupée par le tas est d'environ 500Mb.
Étant donné le nombre relativement normal de threads et la taille de tas beaucoup plus bas que le maximum, j'essaie de comprendre pourquoi je vois cette erreur?
je ne sais pas si cela aide, mais voici la partie supérieure du fichier javacore ...
