Description Ronny Buchmann 2004-11-14 12:13:45 UTC

Description of problem:
Running any of j2re1.4.2-06(SUN), j2re1.4.2-03(Blackdown),
jre-1.5(SUN) results in segfault (1.4.2 immediate, 1.5 while running a
java app).

I'm not able to run it within gdb.

Version-Release number of selected component (if applicable):
kernel-smp-2.6.9-1.667

With UP kernel it runs fine.
There are no kernel messages.
System is a P4 with HT.

You are better off reporting this to the JRE vendors (for Sun go to
http://bugs.sun.com/bugdatabase/index.jsp ) since they have the source and can
see where this is crashing and can determine whether it is actually a bug in the
JVM.

Comment 2 Ronny Buchmann 2004-12-07 18:44:56 UTC

It's ok with kernel-smp-2.6.9-1.698_FC3.

Could the 4G/4G split have been the cause?
