Robert,

thanks for the reply.

The described effect has been seen on WinNT4sp6 and Win2000 (both
workstations).

Thanks for the instructions. The problem is that the effect is shown
after a couple of days incoming HTTP requests to the httpd. Usually
you can not simulate it using benchmark tools like apache's ab :(( --
so an interative approach to get back to a working DLL versions seems
very inconvienent.

That's why I am trying to ask the Cygwin core folks to assist me.
