With hopper b06, on jtgb4u2d ( Sparc solaris 8), tomcat hang after a few iterations.
Processes are still alive. there are gcore files under /bt/Tomcatrun.4427.-d64
on jtgb4u2d.
The failure did not happen in hopper b05.

How to reproduce the bug:

1. start tomcat server
cp -r /net/jtgb4u4c/export/sail8/1.3bigapps/ws/master/dist/tomcat /bt/tomcat
cd /bt/tomcat/bin
export JAVA_ARGS="-d64"
./catalina.sh

2. start tomcat client in a loop
export CLASSPATH=/net/jtgb4u4c.sfbay/export/sail8/1.3bigapps/ws/master/dist/atg/sunperf/urlhammer.jar    
export SERVER=`uname -n`
${JAVA_HOME}/bin/java ${CLIENT_JAVA_ARGS} atg.core.net.URLHammer http://${SERVER}:3030/index.html 100 200 

Or to run tomcat using bigapps script
1. cd /bt
2. export JAVA_HOME=<install dir>
3. /bs/runtomcat.ksh -d64

Log files will be under /bt/Tomcat*/run*out


This looks like another GC failure probably related to the cloudscape p1 bug
and this bugid 4629175.  The server process gets a Sig 11.
