Possible Root Cause 1 : Whenever there is a sequence of XMLs  are gets loaded through batch (through multiple submitter) and different transactions may have to update(access) same set of data in DB. There might be a case when a transaction is acquiring a lock on some data while another transaction is also waiting to fetch the same record then wait time might be reached to maximum time for transaction that is defined  . If this happens then there will be transaction rollback for some transactions and  we might be getting above mentioned errors in batch out logs.

Possible Resolution 1 : Failed transaction needs to be re-submitted through single submitter. and need to execute XMLs manually (one by one) .

P.S. there can be other possible cause of CORBA TRANSACTION_ROLLEDBACK .
