There are a finite number of threads available to CF Server. Lots of CFHTTP
calls are generally a bad idea on most servers because each one ties up a
thread. If, for example, you have CF set for 5 simultaneous threads, and
three or four of them are stuck for minutes at a time, that only leaves one
or two for the rest of the templates to use, and they start backing up in
the que. If enough back up, eventually, they will start timing out with the
"server too busy" message.
