Hi Jeff,
Yes stop/start of the application server does close all the connections to the database.
Lately I did restart postgres too everytime that happened. It did happen in the past, last year sometime when I tried just to close the app and it was not enough. I might mix up different scenarios thought because I did have another issue when the by mistake the max connections were set to 1000 and run out of memory for good reason. So it might have been happened in that case not now.
I will keep you updated.

If I only close the connections the problem is still these so I need to restart postgres.How are you closing the connections?I restart the application server. The problem is that the max_idle connections was set to 1000 on jdbc connection so once the spike happened the app would run with 300 connections and 250 of them or so IDLE for most of the time. I am fixing that
Hi Ionana, thanks for the responses. Does restarting the app server successfully cause all of those connections to terminate? If so, and yet you still have memory problems, then there is still the mystery of where the memory is going.
Cheers,
Jeff
