Hi,
A client of mine has a scheduled event (custom code that I wrote) that sends e-mails under certain circumstances. This scheduled event has been running for approx. 3 years with no issues.
Client is currently running DNN 5.6.3.
The code in the DoWork() function contains code to update a "InProcess" field to "true" in a control table that I use when the process starts and then sets it to "false" when the process is complete. This code was put here in case the scheduler attempted to run again for some reason before the scheduled event was finished.
In two of the last three days, when the scheduled event is run - it appears to kick-off two Simultaneous instances of the event. Users are receiveing two e-mails - both appear to have been sent at the exact same time...
Does anyone have any insight into this issue? I've seen some posts with similiar issues - but not with Simultaneous instances starting at what appears to be the same time.
