An error has just occurred.
To debug, use 'gdb /usr/j2se/bin/java 5439'; then switch to thread 1026
  
Notes
=============
*We still keep the hanging process on above host and go /bt to check the test output.
*How to reproduce bug:
telnet to the hosts shown on the web for linux test machine with root/[host name] as id/passwd
goto /bt to execute script and /bs to get the running results
****take an example from jtg-it2 with vmark problem:****
telnet to jtg-it2 with root/jtg-it2 as id/passwd
execute /bs/runvmark.ksh -server
cd to /bt/xxx.xxx-server to get the results
