Counts the number of Packets of Death — RADIUS disconnect packets — SSG has sent to a RADIUS client. A POD is SSG telling an upstream NAS/client to forcibly tear down a specific session, for example when an admin or AAA server orders a subscriber disconnected, so a sudden rise in this counter reflects an increase in forced disconnects rather than normal logoffs, worth investigating as either a deliberate policy action or a client-compatibility problem. If a bulk disconnect campaign forces 500 delinquent-payment subscribers offline, an admin would expect cssgStatsPODs to jump by roughly 500 immediately afterward.
