Subject "Connection timed out for connection string" flooded the app log
Date Mon, 02 May 2016 15:28:09 GMT
I'm getting this ERROR that is OK, because I lost connection, but it is
getting printed like* 6 timer per MILLISECOND!*.. what configuration can
cause that ??? cause maybe is something that I have poorly configured. but
dont know what it could be


The version I'm using is: 2.9.1

Here is a little abstract of what happened:
