Thanks for response.
The processes that I want to kill have been hanging one one host since I posted the question. Waiting has not been the issue. I should be able to kill any process, regardless of what it may be waiting for. I have not ever had this kind of problem with same code ported to SGI IRIX or RedHat Linux.
I do not know what glance is , but will try to find it.
Most of the unkillables are ssh connections that scripts are using to collect
information from redundant hosts in a group. But I have had instances where
scripts and C compiled binaries have overloaded a system causing me to
attempt cleanup by killing them, but they will not die... thereby mu only recourse was to reboot. These same programs are then fine after reboot.
I was curious as to whether there was a known hpux kernel bug that I could repair.

TKILL(1) LAM TOOLS TKILL(1)
NAME
tkill - Terminate LAM on one node.
SYNOPSIS
tkill [-dhvN] [-f killfile]
OPTIONS
-d Turn on debugging mode. This implies -v.
-h Print the command help menu.
-v Be verbose.
-N Pretend; do not take action.
-f killfile Use killfile as the name of the kill file.
DESCRIPTION
The tkill tool terminates the LAM session started by hboot(1) on the local node. tkill makes use of a kill file created by the LAM kernel,
which contains the process identifiers of every LAM process in ASCII format. A SIGHUP (see signal(3)) signal is sent to every process
listed in the kill file. tkill waits a short period of time for each process to die. By adding the debug option, the user can see the
final disposition of each process. The mission is accomplished if all processes end up dead.
In LAM, the first process to be killed is always the kernel. When the kernel receives its termination signal, it propagates the signal to
all of its constituent processes. Therefore, tkill will ordinarily be racing the kernel to kill all other processes. This redundant
aspect of tkill allows it to be used as a general purpose tool in association with hboot(1).
FILES
/tmp/lam-$USER@hostname the kill file, created by the kernel, where $USER is the userid, and hostname is the name of the local
machine
SEE ALSO
hboot(1), lam-helpfile(5)
