We are occasionally seeing this error:
Cannot open database ''. It may not be a database that your application recognizes, or the file may be corrupt.
This is a Winforms .NET 2.0 product on a Jet/Access DB using Oledb connections.
This error occurs only intermittently. Make the same request a couple of minutes before/after and everything is OK. So we know that in principle the connectionstring etc is fine and the database is up and running and healthy.
Might this be a connection pooling issue? If so, how can we check/confirm this? And what are the steps to resolve. I seem to remember with the Sql connectors in .Net you have some control over the connection pooling whereas with OleDB the connection pooling is built in.
