Hello Guys,

We have the following problem :

The phenomenon

The operation Connection.close() on a Teradata connection sometimes gets blocked forever.

The relevant java stack trace

     java.lang.Thread.State: RUNNABLE

     com.teradata.jdbc.jdbc_3.ifjdbc_4.TeraLocalConnection.
     close(TeraLocalConnection.java:255)

The teradata driver we use

     com.teradata.jdbc.TeraDriver
     From terajdbc4-13.10.00.10.jar

The code that closes the connection

     static public void JdbcClose(Connection conn) { try { if (conn != null) conn.close(); }
     catch (SQLException e) { logger.warn("Unable to dispose of SQL connection properly.", e);
     } }

Can anyone help with this ?

Is there a way to brutely close the thread or call conn.close() with a timeout ?

Thanks,

Ilia
