-----------------------------------------------------------------------
VERSION/DATE: 5.2.3b/2009-05-21


UPGRADE STRATEGY:

- Supports Sun MC Server layer 3.5 Update 1 or newer only.
  You should upgrade SunMC Server layer to '3.5 Update 1' or newer.

- PrimeAlert Agent for Linux 5.2.x versions are NOT backward compatible
  with 5.1.x or older versions. You should uninstall the older version
  before installing the 5.2.x version.


ENHANCEMENTS:

- Added support for SUSE Linux 11


KNOWN PROBLEMS:

- PrimeAlert Agent for Linux is compatible with Sun Management Center 2.x
  agent and infrastructure, thus some features of Sun Management Center 3.x
  agent may not be supported.

  Workaround:  Not available.


- PrimeAlert System Monitor reports on "Idle" processes, and the number
  of "Sleeping" processes does not match the number reported as state
  "S" in a ps -elf.

  Explanation:  The "Idle" processes as reported in the PrimeAlert
                System Monitor module is actually the number of
                sleeping processes that are swapped (in ps -elf,
                the args of such processes are encased in [] ).

                The number of "Sleeping" processes reported in the
                System Monitor module is the number of sleeping
                processes MINUS the number of sleeping processes
                swapped out.


- PrimeAlert System Monitor -> User Statistics -> Console User value
  reports <none>

  Explanation:  The user whose TTY is "console" or "tty1" or ":0" is
                reported as Console User.
                Either there is no user logged in on the console or
                the TTY is not one of the above for the console user.

- Warning message received while stopping the agent:
  "agent process(<PID> error waiting for process to exit: child process
  lost (is SIGCHLD ignored or trapped?)"

  Explanation:  This is benign and can be safely ignored.
                If in doubt, run a "ps -elf | grep paAgent | grep -v grep"
                to ensure that the agent process has been stopped.
