Hi, Seeing as the list is quiet, something that might be of interest.
I am running 2.1.12 on a production server. The server is (was) severly underpowered and the database was straining. I was expenting the normal - "rejecting duplicate request". (Cant remember exact error). Then the server received about 30 access requests in about .1 second It then went into a state where the following appeared over and over in the log: Mon Sep 12 11:33:46 2011 : Info: WARNING: Child is hung for request 647 in component <core> module <queue>.

Mon Sep 12 11:33:48 2011 : Info: WARNING: Child is hung for request 628 in component <core> module <queue>. It never recovered. Had to be restarted. Even with no database queries outstanding. Dont know if 2.1.12 has more "difficulty" with slow databases? Unfortunately dont have more info, so this can probably be ignored.
