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 th= e 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?? Please post the part of your code that uses subprocess.Popen(). Cheers, Chris
