Is alerting working for anybody in 11.5RC3? I'm finding mixed reports on the forums (Some mentions that they aren't working, other people troubleshooting details about the alerts that are firing). For me, it appears they aren't working at all. Alerts that were triggered before the upgrade aren't getting reset (I have since cleared them by disabling and then reenabling the alert), and alerts that should be triggering aren't.
I'm happy to provide more information/examples (and I do have a ticket open), but I'm trying to find out if this is a known issue.
