I have IIS running on Windows 2003
I have process w3wp.exe running at 50-80% CPU. After running iisapp.vbs i found out that process is connected to AppPoolX where single web application named X running.
I did recycle this AppPool and the process remained for some time until i did end process tree via Windows Task Manager while new process for this AppPool was created.
I have screenshot of PerfMon running on this AppPool or direct link here
I did checked IIS logs and seen no attacks or whatsoever, all pages requested normally. If you need other info do not hesitate to ask because i really need help!!!
Where do i start debugging or looking for the problem. 90% identical web site is running smoothly at below 5% CPU at max while it has five times less users.
Help me please.
