          Hi,

          Are you actually using a .NET Stored Procedure, or just a .NET app?
          Are you using 11g ODP/client? I've seen that occur with 11g client due to the new [fault diagnosability|http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28395/oci10new.htm#CHDCIAHJ] feature which is on by default, when an unhandled exception occurs.
          You can turn that beahvior off by setting DIAG_SIGHANDLER_ENABLED=FALSE in the client sqlnet.ora (assuming you're seeing it in a client app) which will make the unhandled exception give a "normal" error stack so you can investigate further.

          Hope it helps,
          Greg
