signals - SIGTERM

Hi all,
I need some urgent help.
we are using Dynix/ptx V4.5 on i386, have several processes and instances are running on the box round the clock.we increased the processes recently.
We have coded to handle the signals in our programs.
Recently, we noticed most of our processes are recieving SIGTERM signal from the kernel and exiting. we can not ignore this signal and the processes are so critical that we cannot have these down for more than 3 to 4 minutes.

Can you please help me in this,

1) When the kernel generates SIGTERM ?
2) can we ignore this safely ?
3) Is there a way to avoid this ?

Your help is highly appriciated

Thanks in advance
Bhupal

KILLALL5(8)						Linux System Administrator's Manual					       KILLALL5(8)

NAME
killall5 -- send a signal to all processes. SYNOPSIS
killall5 -signalnumber [-o omitpid[,omitpid..]] [-o omitpid[,omitpid..]..] DESCRIPTION
killall5 is the SystemV killall command. It sends a signal to all processes except kernel threads and the processes in its own session, so it won't kill the shell that is running the script it was called from. Its primary (only) use is in the rc scripts found in the /etc/init.d directory. OPTIONS
-o omitpid Tells killall5 to omit processes with that process id. NOTES
killall5 can also be invoked as pidof, which is simply a (symbolic) link to the killall5 program. EXIT STATUS
The program return zero if it killed processes. It return 2 if no process were killed, and 1 if it was unable to find any processes (/proc/ is missing). SEE ALSO
halt(8), reboot(8), pidof(8) AUTHOR
