Subject Can not see the stack trace?
Date Wed, 13 Jun 2007 01:59:40 GMT
hi all;
i try to use SIGQUIT but can not see the stack trace.

[root@midtier root]# ps -ef|grep tomcat
root     26337     1  5 09:45 pts/0    00:00:11
/usr/java/jre1.5.0_08/bin/java -Xms256m -Xmx512m -
Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -
Djava.util.logging.config.file=/opt/tomcat/conf/logging.properties -
Djava.endorsed.dirs=/opt/tomcat/common/endorsed -classpath
:/opt/tomcat/bin/bootstrap.ja
root     26427 26172  0 09:49 pts/0    00:00:00 grep tomcat

[root@midtier root]# kill -SIGQUIT 26337
[root@midtier root]# kill -3 26337
[root@midtier root]#

does anyone has idea why?
some artical said that if JVM set -Xrs,it will ignore the OS signal like
SIGQUIT
Does anyone know how can i see the stack trace in this situation?
i use Tomcat 5.5.20 in  linux , java, 1.5.0_10

thanks
