Alert scheduler not scheduling alert as per configuration on splunk 7.2

[graju89]

Hi Every one,
I have upgraded my splunk to 7.2 I am having issues in scheduling alerts. I have saved alert before upgrade which is not being scheduled. The next scheduled time is none. I created new alert to check if it is working. But it also same. For some reason the alerts are not scheduling at all. Cron expression I am using is */15 * * * * to run every 15 min. Is it a know issue on splunk 7.2?

Please help to resolve this friends.

This issue is fixed. The problem was light forwarder on the search head was stopped the scheduler. It is fixed by disabling light forwarder.
