Strange performance issue.

Windows 2008 - IIS7.5
Latest ISAPI REWRITE 3.0

Randomly all web sites will behave slow. Upon further review, we saw that .htaccess and the 3 map .txt files that are associated to every website are being open/read for every request to the server.
Looking at the error.log (with logerror debug)

(Over, and over, with Date being within seconds of each other, in other words, for every single request sent to server.)

It's as if .htaccess file is never cached.

Strange thing is that if the server is rebooted, the issue seems to resolve itself (map and .htaccess load just once).

Hello,

Please put

LogLevel debug

into httpd.conf and show the lines you get.

And also please check Windows Application Event Log for possible errors/crashes.
