I would recommend upgrading the JVM. There's no reason in the world to use
green threads anymore. And on a multi-CPU Solaris box it will kill
performance because the JVM with green threads is single-threaded as far as
the kernel is concerned.
The 1.3 JVMs for Solaris are incredibly fast and powerful. That's probably
your best solution unless you have a really good reason for staying with a
1.1 JVM. Even if, you should upgrade to the latest 1.1.8 production release
and not use the green threads option nor any reference implementation JVMs
(the RI JVMs are not released for production use).
Sun will say the same thing.

Hi Myint,
I am not sure why you are getting core dumps so perhaps someone
else from the group may have an answer???? Perhaps it is time to get SUN
involved?

Hi Dave,
Thanks for your reply. I've checked the web page that "Installation of
Solaris
Patches for JDK 1.1. and Java 2 SDK 1.2 Reference Implementations" from
www.java.sun.com
According to that page, I have installed the following two patches for
Solaris
7.
1. 106980-15 ------- Libthreadspatch
2. 107078-09-------- Xserverbugfixes
And also jrun is being run with native thread but I still got core dumps for
three times on today.
The following is JCP monitor record for that jrun instance.
Please kindly advise me which specific patches need to be installed on my
server
(or) any other parameter need to be changed in Jrun Setting.
(That web server memory is 1.5GB and swap memory is 5GB.)
Thanks in advance.
Regards,
Myint Myint Moe
