Running CF 9,0,1,274733 and I must qualify my post by saying that I know enough about CF to be dangerous.
We have a number of schedule tasks that run once per day at different times of the day. These tasks do things like query the database and email staff about low on stock items and almost expired items, etc. We installed some critical security updates on our Win 2008r2 server a few days ago and the double emails started that night. I don't want to uninstall those security updates to fix this issue.
Here are some things I have checked and tried:
a) I cleared the cache in CF Admin.
Clear Template Cache Now
Clear Component Cache Now
Still getting dupes
b) Restarted the CF services in the services.msc in Windows. Still getting dupes.
c) Restarted the server. Still getting dupes.
d) I ran a few of the tasks manually by clicking the Run button in the CF Admin Schedule Task list. Still getting dupes.
e) I added the spoolenable="no" attribute to the cfmail tag. Still getting dupes.
f) I recreated some of the tasks and the cfm pages that they point to. I turned the old tasks off by setting them to "One-Time". Still getting dupes.
g) I created a new task and a new cfm page with just the cfmail tag. No cfquery, no cfloop, no cfoutput. Just the cfmail tag with 1 sentence in the body. Still getting dupes.
h) I changed email addresses in the cfm pages. Still getting dupes.
i) I checked the mailsent.log. It shows these task pages are being fired twice about 1-2 minutes apart. If the task is set to run at 11:00pm then it runs at 11:00pm and at 11:01pm. It is also runs twice and 1 minute apart when I click the Run button in the task list. This looks like a CF issue and not an Exchange issue.
I hope someone can point me in the right direction. Thanks.
