How to reproduce the bug: ( The bug is highly intermitten, it may be
very difficult to reproduce it ) I saved the test log along with core files
under /net/jtgb4u4c/export/sail6/bigapps_log/solaris/hopper_b13/jtgb4u2c
1. telnet to jtgb4u2c
2. export JAVA_HOME=<your java home>
3. run the script /bs/runtomcat.ksh -server
4. go to /bt/Tomcat*server to view the log files. If the file "run.tomcat.out"
is not up-to-date, the app probably crashs.

The failure showed up in build 18 on jtg-e250-2 (Solaris Sparc) after 18 hours.
it's failing in a I2C Adapter.
The processes are still alive on jtg-e250-2.sfbay. I also saved gcore files
under /bt/Tomcat*
