Trapped Signal HUP

We encountered an issue in our project while using the Interix UNIX (SFU 3.5) and explained our query below. We would be happy if anybody helps us to troubleshoot the problem J

In our code the trapping signal for all signals like HUP, INT, QUIT, ILL, TRAP, ABRT, EXCEPT, etc., is initialized in the main script. This main script calls the various executable codes and shell scripts which are mostly used to connect the ACR data base and transfer the files from local machine to remote machine.

While execution of our code sometimes we received message like Trapped Signal HUP and sometimes it was executing fine. Could any of you please explain us, why we have received message Trapped Signal HUP in some occurrences and not in some other times for the same executables?

For example,

trap_function()
{
SIGNAL=$1
echo Trapped signal $SIGNAL >> $HOME/Trap.log
trap - $SIGNAL
kill -$SIGNAL $MYPID
}

for SIGNAME in \
HUP \
INT \
;;;;
XCPU \
XFSZ
do
trap "trap_function $SIGNAME" $SIGNAME
done

MYPID=$$

./script1.sh &
./script2.sg &
./script3.sh &
........
......
./exe1 &
.....
./script30.sh &
./exe5 &

Note:All log files which sizes are greater than 200kb will be taken backup.

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
