Coldfusion neo-cron.xml has been modified - when it hasn't been

Question

We've just upgraded from CF 9 to 9.0.1 (ColdFusion 9 Update 1). We're running on Windows Server 2008.

After the upgrade we noticed on our server that we were getting a lot of these messages in server.log:

"Information","scheduler-6","10/05/10","12:34:48",,"neo-cron.xml  has been modified . Reloading the service coldfusion.scheduling.CronServiceImpl@c020a"

We have not touched the neo-cron.xml file, but since the upgrade, every few hours CF thinks the file has been changed.

We probably would not have noticed this only for the fact that for a period between 2 of the reloads all our scheduled tasks were being executed twice! However, after another reload of neo-cron.xml the duplication stopped.

Has anyone else come across this issue?

Thanks in advance.

PS: Enable logging for scheduled tasks in CF admin is not enabled.

Hi,

I'm not sure about the doubling up of tasks, but I also noticed that neo-cron.xml was constantly being modified.

Looks like they've added a new node to each task, last_run, which is updated after each execution of a task.
