I have created a saved search which is meant to email the results to me, but it has only worked intermittently. I have checked $SPLUNK_HOME$/var/log/splunk/python.log. When successful, the email is logged. There are no failures logged so it looks like it doesn't try to create the email.
If I check the Jobs window, the search shows as Done. It returns the results to screen when run manually but does not generate the email. I have tried changing the permissions on the search to Global allow. No good.
