*                      application server via admin console,   *
*                      wscp, or XMLConfig, sometimes the       *

* RECOMMENDATION:                                              *
****************************************************************
When user stops an application server via any of the
WebSphere client programs, WebSphere reports that the
application is stopped but looking at the process table
of the system (e.g., "ps -ef"), the process remains active.
Problem conclusion
Changed the code so that process is terminated with SIGKILL.
Original code did something like:

  if (kill(app server pid, SIGTERM)!= 0)
  {
    . . .
    kill(app server pid, SIGKILL);

Problem was that return code of "0" from kill() does not
mean that target process is terminated - only that target
pid exists, user has permission to send signal to target
process, and signal number is valid.
Temporary fix
Temporary fix available in cumulative system management eFixes
dated 20Dec02 or later.
