why a process ( written in c++) taking 200% cpu usage?

Running a (c++) game application process (server)(multi threaded) under RedHat linux version 2.6.18-8.1.15.el5, which is using mysql db version 5.0.27.GUI is written in flash(client). Client communicates with server thro' socket. C++ Process is running successfully for 2 days, but cpu usage of this process has been increasing gradually and reaching 200% and at the end of 48hrs, process has not been responding.But if i check the status using ps command, it shows status running.Why process is not responding after 48hrs? Why the cpu usage increasing?

The 200% usage simply means that the process is running both CPU cores flat out. Without knowing what the application is, it is anyone's guess as to the problem causing this. My guess is that it is starting threads and not ending them, but this is pure speculation.

Yes. I solved this issue. Now cpu usage is normal. Thank You.
