My ColdFusion Administrator is suddenly not working. What does this error mean?

Question

Server Error The server encountered an internal error and was unable to complete your request.

Application server is busy. Either there are too many concurrent requests or the server still is starting up.

Answer 1

Either there are too many concurrent requests or the server still is starting up.

Usually, I see this messsage shortly after a restart. Are you sure, the server didn't restart?

Answer 2

I haven't seen this error, but my guess would be that the Administrator needs access to a locked resource. I would try restarting CF services, and maybe the whole server.

Answer 3

I agree that this question more belongs on ServerFault.

This error message typically means that the web server (IIS, Apache, etc) is having trouble communicating with the App Server (ColdFusion). This can be the case if CF is mid-restart, or if it is crashing during start.

You need to check log files for clues as to what might be going on. Start with:

{cf-install}/logs/server.log
{cf-install}/logs/cfserver.log
{cf-install}/runtime/logs/coldfusion-event.log

It would also be helpful if you specified what version of ColdFusion you're running (8? 9? 5?), and how you've got it installed (standalone, multi-instance, WAR, etc).

Answer 4

This happend with me few times, when I restarted CF11 applications services, it shows error and keeps status as "Starting..." When machine is reboot, it automatically turns on and works. Until then, it still shows either no services available / too many concurrent request.
