Error 500: The Metrics service is not available.

On my production server (Windows Server 2008 R2 Web edition 64 bit, 4 GB RAM, Coldfusion 9.0.1 32 bit) every 4-5 days all websites aren't available, the error message is:

ERROR 500:

After a server reboot all work fine for 4-5 days and the problem comes again. The metric service is enabled (http://kb2.adobe.com/cps/191/tn_19120.html), somebody have an idea to solve this problem?

My CF configuration is:

Timeout Requests after ( seconds): 300

Maximum JVM Heap Size (MB): 1024

JVM Arguments:

-server -Dsun.io.useCanonCaches=false -XX:MaxPermSize=256m -XX:+UseParallelGC -Dcoldfusion.rootDir={application.home}/../ -Dcoldfusion.libPath={application.home}/../lib

Use J2EE session variables

Thanks
