Segfaulting Java process

Question

J'ai un processus Java qui fonctionne sur un grand ensemble de données en mémoire. Je l'ai vu s'écraser avec un signal SIGSEGV parfois, donc je me demandais quelles pourraient être les causes et les correctifs potentiels.

caues:

• machine virtuelle Java bug
• bug bibliothèque native (par exemple pthreads etc)
• bug JNI dans le code utilisateur

de Correction:

• Mise à jour à nouveau JVM

Dans mon cas, c'est la sortie forme le fichier journal (élagué)

Answer 1

Vous feriez vraiment besoin de préciser quel code il s'écrase. Cela ressemble à un problème lié à JNI mais à la surface.

Answer 2

Corrections: - Mise à niveau vers une nouvelle machine virtuelle Java

Eh bien avez-vous essayé les dernières versions de la machine virtuelle Java?

JRE version: 6.0_14-b08

La dernière version est 1.6.0_19.

Answer 3

Vous dites que vous travaillez sur "un grand ensemble de données en mémoire", et que votre sortie inclut le démon "JavaThread 'Low Memory Detector". Autorisez-vous assez de mémoire pour ce que vous essayez de faire?

Answer 4

La segfault se produit-il sur plus d'une machine? Si ce n'est qu'une seule machine, cela peut être un problème matériel, probablement une RAM défectueuse - essayez d'exécuter memtest.
