80% CPU utilization without active http connections





------- Additional Comments From wrowe@apache.org  2003-01-22 16:17 -------

  Very little changed in the 'sleeping' accept loop;

http://cvs.apache.org/viewcvs/httpd-2.0/server/mpm/winnt/child.c.diff?r1=1.6&r2=1.9

  That code works around some network filters (e.g. firewall & antivirus 
  software) which abused the result code from AcceptEx().

  Because that accept code is optimized for the native Win32 WinSock2 API, it
  doesn't use the APR network code at all.

  Likewise, the service manager code has no significant changes (it runs it's
  own thread waiting for service control 'wakeup' events.

http://cvs.apache.org/viewcvs/httpd-2.0/server/mpm/winnt/service.c.diff?r1=1.57&r2=1.58

  Do you have any interesting (read: 3rd party) modules installed on this
  server?  Also, please check your error log for unusual activitiy... you
  might even want to set the directive LogLevel debug just so you see the
  low-level errors.  (If you like, *attach*, don't paste, a relevant chunk
  of that log to this report.)

  Open the task manager, and choose 'View', 'Select Columns...' and add 
  'Threads' to the list.  This will help you identify for us if the parent
  (a couple of threads) or the child (many threads) is having problems.
  Please update the bug report when you have more clues.  Thanks.
