Notes
=============
*We still keep the hanging process on jtg-linux12 and go /bt to check the test output.
*How to reproduce bug:
telnet to the hosts shown in web for linux test machine with root/[host name] as id/passwd
goto /bt to execute script and /bs to get the running results
****for example:****
telnet to jtg-i114 with root/jtg-i114 as id/passwd
execute /bs/runatg.ksh -server
cd to /bt/atgxxx.xxx-server to get the results
