Original- Hi All,
i have had issues since upgrading from 6 to 7 with
cfschedule. sometimes it runs fine, other times it will run the
same task multiple times in a row, other times it will wait an hour
then run the same task again.
This may not sound like a big deal, but the tasks send out
several thousands of emails. talk about spam!!
I have been screamed at on a weekly basis to make this stop.
Now since the the DST change, the tasks that were scheduled
at 3pm run at 3pm and again at 4pm!!
Please someone help!!!!!!!!!!!!!!!!!!!!!
Thanks in advance.

Hi BK,
in my task is setup to run every 15 with a start date of a
few days ago and no end date or time.
it calls a file on the same server via its dsn name.
The file it calls is this:
[code]
<cfset testtext = "Testing st #now()#">
<cfset testSTname = "d:\st_test_" &
#DateFormat(now(),"yyyymmdd")#&""&#TimeFormat(now(),"HHmmss")#
&".txt">
<!--- <cffile action="write" file="#testSTname#"
output="#testtext#" nameconflict="makeunique"> --->
<cfmail to="[email protected]" from="[email protected]"
subject="st timer test">
#Dateformat(now(),"mm/dd/yyyy")#
#TimeFormat(now(),"hh:mm:ss:l")#
</cfmail>
[/code]
If you notice i commented out the file write. something was
puzzling about it, it would write fine for an hour then once in
awhile write multiples (by comparing the date created on the file
in windows.
I then found the calls in my IIS log file, every single call
was done twice at exactly the same time.

So i decieded to make it send an email, this way there is a
queue so to speak for the messages to be written, i think this is
why i saw speratic multiples with cffile.
Email 1 contents: {ts '2007-07-31 01:30:00'} 01:30:00:769
Email 2 contents: {ts '2007-07-31 01:30:00'} 01:30:00:909
So far, i am only getting 2 copies for every fire of the
task, but i have seen in other tasks that email, up to 6 copies.
i can see this in IIS Logs, the test cfm file being called at
least twice per task for long periods, then other tasks will fire
and i only see a single call to the test cfm file. but its next
execution time is duplicated if there is no other tasks running
during the same time period
I have dug through all the logs for each task, so far all of
the task that have no end date fire multiple times.
I can see the results (files written, db records inserted,
emails sent, IIS log files).
all show duplicates during same creation time Except the
scheduler.log it only shows each of those tasks firing once.
I can only assume that the scheduler log is being updated
correctly which leads me to belive that this log entry is done some
time before the scheduler payload execution or the scheduler code
dosnt log multiple triggers on its actions.
So i am going to set the End date for this test task to see
if the duplicates stop.
more to come
