I have isolated all my Firebird code into a single webservice module and are using very basic using() { } pattern to access the database.
The error happens sporadic after some time (if it happens) but is reproducable in the way that you can sort of guarantee that it will start happening after some hours max.
As soon as I use Visual Studio 2013 and driver version 4.5.1.0 or below it will NEVER happen (running for days and weeks)
As soon as I use Visual Studio 2013 and driver version 4.6.0.0 or above it WILL happen (after minutes or hours max.) It is very BAD as soon as it happens!!
As soon as I use Visual Studio 2015 (no matter which driver version) it WILL happen!!
.Net Framework version 4.5 4.51 4.52 4.6 does NOT matter!!

sample code:

using (var context = new VodmateEFCtx())
{
return context.DOWNLOADS.SingleOfDefault(x => x.dlcode = "xxxxxx");
}
