Michael, Most obvious questions first - what version of CF are you running, do you have the latest patches and have you updated your database driver (esp. for CFMX 6.1)?
More likely than anything, it's one of the applications on your server. Try logging slow requests via the CF admin setting and check the log after a few days. Check for un-varred variables in cffunctions (with the excellent var scope checker). Look for infinite redirects. That sort of thing. Look for similar debugging tools on your database. A lot of these issues come when you're using an external system, like a web service, database, c++ cfx tag or the like. Consider this while asking yourself where the trouble spots *should* be. Worst case, it's a hard-to-duplicate bug involving multiple users doing similar things. A bit of debugging work and you will find the issue eventually. -- nathan strutz http://www.dopefly.com/ On Feb 8, 2008 3:24 PM, Michael Muller <[EMAIL PROTECTED]> wrote: > Every once in a while my server's CPUs go nuts.
