Problem with CFM 7

Hello Guys ,

I am new in this forum and i have a problema with coldfusion.

I have many sites in my CFM Server. A have a Windows 2003 SP2 32 Bits and ColdFusion MX
Version 7,0,2,142559.

Eventually, we received an error message for any failure in JRun. Usually ODBC driver of the machine failure and restore the access only after restart IIS Services and CFM.

How solve this problem?
Is there a good article on how to optimize the resources of the server?

Thanks
