You should be looking for code that "waits" for a response from a third party process. Culprits are (typically) db
access, ftp, ldap, pop, file access (cffile), cfhttp etc. All of these services must connect to a service or process
"outside" the CF engine - cf awaits their response... sometimes indefinitely if its set up that way. That's why such
tags often include a "timeout" value. Slow pages is a good place to start. Also look at the scheduled task folder and
find out if there's a regular "data import" or web scraping application or some other ap put there for utility reasons.
Sometimes these tasks run for years with no one noticing them and then suddenly start hanging.

Subject: Help with CF5 Queued Requests
I have been tasked with stabilizing a legacy CF 5 application which had several problems including CF restarts and
loss of client variables etc.
I managed to solve most of the issues -- many caused by application variables not being locked.
There is one issue which I need help with. Using Perfmon, I notice that, at times, ColdFusion requests stay queued and
are not processed. They just stay there - forcing me to restart CF.
I am tryng to track down what in the code could be causing this by looking at the log entries showing slow page
warnings.
Is there any known causes for this symptom? What else should I be looking for?
Thanks for your help.
Frank
