Lalit, A process's priority is constantly changing based on its nice value and how much CPU time it's had or how long it's been since it was given CPU time. It's how the scheduler decides what process to schedule next on the CPU. The longer the process hasn't had CPU time, the higher its priority will become. Once its priority gets high enough, the scheduler will give it some CPU time. The longer it has been running on the CPU, the lower its priority will become, until it gets low enough for something else to have a higher priority at which point it will get moved off the CPU in favor of the other process.

I can see in 'top' that its PRIORITY is somewhere near 236-255 with NICE vlaue at 20. There are other process running at priorities at 154, 156 but my daemon always remain at top of the list. Why? Also i witnesssed that after few minutes of execution the PRIORITY is changed to 152. Why does it change from 242/255 to 152? Is there any system call through which i can FIX the Priority for my Daemon? Many Thanks _________________________________________________________________ Mergers, takeovers, buyouts.
