It turns out that it was part DBD::Pg and part our app (a big part). A plugin for the app creates a separate db handle which listens, but never does anything with the notifications. Apparently, the recv-q cleared whenever a request was made via this plugin (which is rare for most people who use this), but nothing was processed, so notifications would build up. If they're left running for that long, then they get into the bad state. We fixed our app to not have the plugin's db handle listen (it was pointless to have it listen anyway) and all seems well. While it may technically be a bug that a database handle will get into this state after ~800 unprocessed notifications, I'd say that's much more the fault of the application programmers. Anyway, thanks for all your help. Peter ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
