1) This looks like a bug in MSDART.dll (part of MDAC). Try installing the
latest version (2.
. If that doesn't resolve it, you will likely need to
open an incident w/MS-Support.
2) Since you make a lot of calls to Jet (Access), I would recommend that you
change your connection string to be OLEDB instead of ODBC b/c it performs
much better. Also, you should be running compaction on the DB at least once
a week (improves perf as well).
3) You should also take a moment to install the Jet updates. This won't
affect this problem, but may prevent others.
Also, I would recommend disabling the ASP thread gating.
