Thanks a lot for your efforts I will apply these changes and let you know the outcomes. meanwhile I ran the same script on my sunSO server and surprising there it was taking only 4 to 5% of cpu..on the other hand on my Linux server it was taking 99 to 100%.. why there is such a large difference... and it also shows that there is not much wrong with our script.. also please fiind my server details.

Linux server where I am supposed to run the script and its causing issues...
