TrapHandle - Fork & Inform Ack

Hi,

I am using snmptrapd to receive informs. I noticed that snmptrapd sends 
Inform Ack only when the 'traphandle' (specified in snmptrapd.conf) finishes 
the job.
Is this behavior correct?

I am trying to make sure that Ack is sent 'before' my traphandle process the 
inform-request.

In my case traphandle is a unix shell script. To make sure ack is sent first 
I tried running my traphandle in background , even tried exec(ing)!

This does not seems work for me.

Can any please give any suggestions to get it working !! 


--- snmptrapd.conf ---

traphandle default /tmp/trapHandle.sh

--- snmptrapd.conf ---



--- trapHandle.sh ---

#!/bin/sh

# do something something

exec myprogram &
# also tried myprogram &

exit 0

--- trapHandle.sh ---


thanks
