Access violation in module 'BANTAM.DLL'

I have written a server application that is communicating with multiple
MS-DOS PC's via ascii format. We use TbatchMove to generate ascii files from
oracle 7.3 and Paradox 7 databases.

The message Access violation at address 4E8E5Cdd in module 'BANTAM.DLL'
occurs approximately every 200 times TBatchMove is executed.

I have not yet been able to understand why this Access violation occurs.

Can anybody help with some information ?
