I had an issue last night where my MySQL DB crashed, and upon rebooting the DB server, I can get to the Centreon portal page but none of my pollers appear to be working. It looks like they're working off of stale information. The Pollers page shows my pollers as "Running" but the tooltip says they are not running. It would appear the checks are in a stuck state. I don't even know where to begin troubleshooting this issue, I've attempted to restart the Nagios service on all pollers.
