So I recently had this issue with running out of DB connections to my postgresql server.
Now i figured out that egroupware by default has persistent connections enabled (for performance reasons). Which for a small installation with 2 users and a few cal/cardDAV sync devices really is not an issue .. so after checking that egw hat 25+ persistent connections I decided to just disable persistent connections.
The result: less resources consumed on my DB server, free connections for other things that actually use them and absolutely no noticeable issue or slowdown with egroupware.
So my recommendation for small installs of egroupware: do not enable persistent connections.Share on Twitter Share on Facebook
