Exception: Pushing object second time

Post by rupprecht » Wed 22 Nov 2006 08:35

Hi folks,

the following exception showed up two times already within our application:

Exception: System.InvalidOperationException
Message: Pushing object second time
Source: CoreLab.MySql
at CoreLab.Common.DbConnectionInternal.b(Object A_0)
at CoreLab.Common.DbConnectionPoolGroup.a(DbConnectionPool A_0)
at CoreLab.Common.DbConnectionPoolGroup.b(Object A_0)

Our email to support has not been answered.

Any ideas ?

Please describe the problem in detail.
Send us small test project if possible to reproduce the problem; it is
desirable to use 'test' schema objects, otherwise include definition of
your own database objects. Use e-mail address provided in the Readme file.
Do not use third party components.
If it is impossible for you to create test project please send us a piece of
your code where the error occurs.

I am sorry but we are not able to provide you with a demo project. Your component is working in a big material handling system where the described error occurs. We are not able to reproduce the error in our office.

However, the exception occurs during a timer event in your code while we are not doing anything with the database. The exception does not seem to be an exception from .NET classes but from your classes.

Your help is highly appreciated as we are dealing with a very expensive production system that does not run stable.

Regards, Chris

What product do you use? If you use MySQLDirect, please create a new thread in appropriate forum. Can you spot the circumstances under which this exception occurs?
