Hi,
Recently we discovered in our production server this kind of
exception :
We are wondering what causes the transaction to be zombied, and why do
we get a nullreferenceexception in this method ? As you will see in
the call stack, at every 5 minutes (timer), we are inserting data in a
transaction. In a day, we can have 2-3 occurence of this problème.
