Hey, I just learned about the pool events and with their help I can see that MediaCore will retrieves multiple connections from the pool but not all connections are properly returned by the end of the request...
In the end the culprit was a bad ToscaWidgets form: CheckBoxList('groups', label_text=N_('Groups'), options=Group.custom_groups(...).all), That somehow got a new connection from the pool at class load time (= when MediaCore was started) but the connection was never returned. Just writing these posts somehow help understanding/solving the problem - though I am sorry that I didn't find out until after sending the message. fs -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
