frozen application / kill -3

[christian]

Hello,

my application runs from time to time into a frozen state. I've found
the "kill -3
process_id" command to get the stacktrace but if the customer starts
this command after reaching the frozen state he gets no answer. The
kill -3 command was started in the same console as where the process
was started.

the application runs with jre 1.4.0 on solaris 8.

Has got anybody any ideas?

While trying the command on a running application it prints the needid
stacktrace...

Are there other methods to get the stacktrace of a frozen application?

Thank you!

May be a siily question, but: did you try issuing the kill -3 command in a
_different_ console?

Yes, but we still kept open the console window where we started the
application.
It doesn't matter where to start the kill -3 command. the output
should appear in the window where the application was started. The
application is not interactive started -> &

Know we created a core file with <ctrl><\> but this is not the
stacktrace...
