I have narrowed down the issue we are using gzip in the script ..to compress the file ..we write to the pipe then we will compreess using gzip
below is the sample code

#!/usr/bin/ksh

/usr/sbin/mknod NAMEDPIPE p

gzip -1 < NAMEDPIPE > EXPORT &
db2 "export to NAMEDPIPE of del select * from test" ##db2 command to
## export data
rm -f NAMEDPIPE


After completion of the script , successfully , i still see the script PID , i don't see connection any connection to DB , Basically script is hanging in there doing nothing , I suspect gzip -1 < NAMEDPIPE > EXPORT & not termenating ....properly

Thanks
