How to debug SIGSEGV in jvm

914818Feb 2 2012 — edited Feb 3 2012

Hello,

We are running into SIGSEGV from time to time. (Not 100% reproducible)
In every case, the fatal error log shows that jvm crashes in libjvm.so called from sun.text.normalizer.NormalizerImpl.
Could you kindly advise me how to prevent this happening again?
