Обсуждение: Error 25P02 - transaction aborted - Potential causes?

I've started to get the following error:

25P02 - current transaction is aborted, commands ignored

This error occurs on a 'select' statement done within a transaction, after multiple selects and updates have already
beenmade. The application is written in VB.Net, and uses npgsql for data access. (I'm running postgres 8.2). 

Does anyone have any idea what the cause of the error could be? Is there any chance that its because Postgres needs
morespace for doing rollbacks? (If so, how is this space increased). 

Or, is there any change I can make to the way I do the transactions that will help? Currently, I'm using the following:

    Dim conn As Npgsql.NpgsqlConnection
    Dim Trans As Npgsql.NpgsqlTransaction
    conn = New Npgsql.NpgsqlConnection("my connection string...")
    conn.Open()
    Trans = conn.BeginTransaction

Are there any parameters to the transaction that I can use that would prevent this error?

This is symptom not cause; what you ought to be asking is what caused
the transaction to fail in the first place, ie the error before this
one.

If you think there wasn't one, that might be an indication that your
app code is failing to check for error somewhere that it needs to.
You could turn up the logging on the server to see what is happening.
