kill -3 on RedHat AS 2.1 does not work

hrraju · 10-19-2004, 02:05 PM

I have a java process running on RedHat AS 2.1 and I wish to get a thread dump of the java process.
I have tried the following :
kill -3
Ctrl + Brk

I don't see anything happening on the console where the java process is running. Is the thread dump being redirected to some other file ? or is there some other way to get a thread dump ?

Thanks,

After some more investigation, I have found this problem to be only with JRE 131(hotspot,server,client mode).
I get the thread dump when I use JRE 1.4.1

So, this looks like a JRE specific issue and not the OS.

But still if anybody knows of any option(Ex. -X options) I need to set with JRE 131, that would give me a thread dump, please let me know.

Thanks,
