unspecified error - due to open dataconnections ?

[kate_cha]

Hello,
I'm new to .net, so this may be a really easy question....I have been
working on a .net application - each web page pulls information from a an
access database and writes it to the screen. Mostly this is done using a
command object and a datareader. The data can also be edited - also using a
command object and the executenonquery method. There is one page that uses a
repeater.

This works fine with no errors until you have viewed and updated a number of
pages, when it throws an error:
[OleDbException (0x80004005): Unspecified error]

The stack trace is:
System.Data.Ole Db.OleDbExcepti on: Unspecified error

I have set the command objects to nothing after I've finished with them, but
I was wondering if there was something else in this vein that I need to
do....any help would be much appreciated!!
