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?
Dave
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

You can specify the thread model as a switch when you run java as
in java -native/-green depending on what you want. Another way to set
it up would be to set up the environment before calling java by
% setenv THREADS_FLAG native.
From personal experience I would make sure your version of Solaris
has the right patch level(very important). Check javasoft for more
info on the required patch level.
