[dba-VB] Unspecified Error

Hi All --

After several hours (~6 hours Win7 64bit, ~24hours WinXP) of running
multi-threaded (.NET Framework 3.5 SP1 WinForms) desktop application using
.mdb files as backend I'm getting the following runtime error:

Exception -> Unspecified error

StackTrace ->    at

constr, OleDbConnection connection)

It looks like this is an OleDbProvider bug.

Have you seen/experienced something like that?

Context:

1. I do exclusively use

using (OleDbConnection cnn = new
OleDbConnection("{{mymdbConnectionStringHere}}"))
{
    cnn.Open();
    ... 
}

2. I do use IN clause in some select SQL expressions to point to external
MDB tables.

I guess the issues is caused by case (2). Although that's still a hypothesis
here to check (some code fixes are needed in the core code of my
application, and I'm considreing now will that be worth fixing, or I should
better switch to MS SQL backend.)

Thank you.
