OLEDB Debugging

i'm using an ASP.NET 2.0 app (running in a Windows Server 2003 environment) connection to an informix db using IBM Client Provider.

The app work fine and pretty fast but I'm experiencing random oledb connection error like this :

no error message available, result code: -2147417851(0x80010105).

Stack Trace: at system.data.oledb.oledbconnectioninternal..ctor(oledbconnectionstring constr, oledbconnection connection) at system.data.oledb.oledbconnectionfactory.createconnection(dbconnectionoptions options, object poolgroupproviderinfo, dbconnectionpool pool, dbconnection owningobject) at system.data.providerbase.dbconnectionfactory.createnonpooledconnection(dbconnection owningconnection, dbconnectionpoolgroup poolgroup) at system.data.providerbase.dbconnectionfactory.getconnection(dbconnection owningconnection) at system.data.providerbase.dbconnectionclosed.openconnection(dbconnection outerconnection, dbconnectionfactory connectionfactory) at system.data.oledb.oledbconnection.open() at hltlib.oledbdatabase.initcommand() in c:\hltdesktop\hltdesktop.legacy\oledbdatabase.cs:line 62

The only way to make this error disappear is to reset IIS.

Have anyone never had this problem ? Is there a windows oledb debugger and/or tracer that i can enable to troubleshoot this problem ?

I guess it could be caused by the OLEDB connection pooling/its implementation in the Provider. Try to disable OLEDB services in the registry to prevent the connection pooling for the provider. See MS documentation on how to do this. HTH
