I have the same problem in W2K starting with at least with two cygwin
services, where one cygrunsrv.exe after some days goes up to 99%.
Killing the cygrunsrv.exe process alone is enough, which did
not affect the actual service, which runs fine even with the killed
service controller.
With one cygwin service alone I had no problem so far.
Regardless which service, if it's sshd, cron or cygserver.

No problem on the XP boxes.
