Description

Greetings List.

I have searched a lot for information about this Warning I am getting when I
start up tomcat by using jsvc on my Fedora Core 4 platform, but I have not been
able to find anything that helped me solve my problem. So now I am reporting it
here.

I am using the Tomcat5.sh script supplied in the native folder.

I have tried 2 different scenarios:

1. running jsvc with "-user tomcat"
2. ommitting the -user option entirely (running it as root)

In scenario 1 I get the warning:
"Java HotSpot(TM) Server VM warning: Can't detect initial thread stack location

• find_vma failed" (same message if I use the Client VM).

I do not get this warning in scenario 2.

If I use the script "catalina.sh" as the user tomcat I can start up the
webserver fine without warnings (though not on port 80 naturally).

System is Fedora Cora 4
Tomcat is the the apache-tomcat-5.5.15.tar.gz
JDK/JRE is Suns jdk 1.5.0_06 for linux (rpm distribution)
(note I dont have any other java distributions installed, so fedora RPM name
clashes is not an issue)
