Can not see the stack trace?
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

Are you actually using -Xrs? At least it's not contained in the part of
the commandline you posted, which is unfortunately truncated.
The result of kill -QUIT goes to STDOUT of the jvm. So you need to find
out, where your STDOUT goes to. The standard tomcat start scripts
(startup.sh or catalina.sh called with the argument start) redirect
STDOUT to logs/catalina.out.
