LAMCLEAN(1)                      LAM COMMANDS                      LAMCLEAN(1)

NAME
       lamclean - Attempt to clean entire LAM system.

SYNOPSIS
       lamclean [-hv]

OPTIONS
       -h      Print the command help menu.

       -v      Be verbose.

DESCRIPTION
       The lamclean command attempts to remove all user processes and messages
       from all nodes.  It also de-allocates all user allocated resources and
       cancels all user process registrations.  This happens by invoking many
       different remote services which have previously been invoked
       individually by several other commands.  These commands should still be
       used when partial selective removal of user presence is desired.
       Otherwise, lamclean is a quick and convenient way of starting over
       after a bad application run without rebooting the system.

       lamclean takes the following actions on the following system processes
       on all nodes:

       kenyad         The LAM SIGUDIE signal (terminate) is sent to all user
                      processes.  See doom(1).

       bufferd        The entire daemon is reset to its initial state after
                      booting.  See sweep(1).

       filed          All user file descriptors are closed.  See fctl(1).

       traced         All traces are removed.  See lamtrace(1).

       lamclean will not succeed if any of the nodes are unreachable due to
       catastrophic failure or maximum buffer overflow with link jamming.  If
       lamclean does not return, use lamwipe(1) and lamboot(1) to restart the
       multicomputer.
