Hi,

I am using subprocess.Popen to start a movie ripping command HandBrakeCLI. My server is 64bit ubuntu server and has 8 cores. When the command starts it uses all 8 cores upto 80%-100% and works fine, but after 270 seconds the cpu usage of all the cores drops to 0% - 1%. I tried this many time this happens exactly after 270 seconds. Is there some predefined timeout??
