Resolution:
==========
This could be resolved by

1).Changing the values for the connection poolsize and the maximum transaction timeout in the WebSphere console to to be 40 and 0 respectively. 
2).Increasing the ecmdatasource transaction timeout parameter in the stand.

In TIBCO MDM, DBloader fails to import records with a CORBA TRANSACTION_ROLLEDBACK exception.
