chroot Linux 2.4.20-8 and tomcat 5.0.27
We are trying to run tomcat 5.0.27 in a chroot jail on Linux 2.4.20-8 .
When we start tomcat we always get the following error message:
> Java HotSpot(TM) Client VM warning: Can't detect initial thread stack
> location
About 50% of the time its worse.
> Java HotSpot(TM) Client VM warning: Can't detect initial thread stack

We get the same error running any java application with chroot. I'm
pretty sure this is because some file with important information is not
available inside our chrooted file structure.
Does anyone have a solution to this problem?
Thanks,

Thanks Oliver, that did the trick. I had the feeling that was the
directory I needed but for some reason I tried to make a new copy. What
was I thinking.

Just for checking, have you mounted /proc in the chroot ? It is a source
of valuable information for any program running inside the jail and
could explain the misbehaviour.
"mount -t proc /proc proc" as root in the chroot

Sjoerd,
Thanks for your input. We installed Java within the chroot jail and are
still having this problem. I have no problem increasing the stack size
using Xss but I have no idea what property sets the initial thread
stack location or which would allow us to allocate stack guard pages.

Did you install Java within or without the chroot jail?
If it is without the chroot jail, it can't detect certain configuration
files, with the abcense of these, it doesn't know how to initialize
itself. You could either:
Use the parameters for the java executable
Copy the needed configuration files (property files)
Install Java within the chroot jail

Sjoerd
