May I know what causes ncsvc to run and what is this program anyway ?

It looks like it is a Juniper VPN

Does this help ?

Yes. I think it is strongly related to vpn. I don't know why the process
is started automatically. I just left the linux box for a while and the
process starts to run and it is causing the poor machine to turn on the
fan and make a lot of noise.

I top, get the id , and kill it. But then after that my firefox cannot
connect to the internet. So I have to reboot the system and it is okay after that.

I would say this happens very rarely. I don't know if it is worthwhile to find the exact cause. May be I will contact the guy in my company to find out his opinion.
