Very Urgent : Dumps Generated in Production System, reason unknown

We are getting ABAP Dumps every second for some reason on the production system. The error analysis message is as follows :

Error analysis

The data type "MCVBAPB" was reloaded from the database while the program

was running.

However, the system found a version of the type that was newer than

the one required.

Any pointers to the reason for this will be helpful.

Kindly contribute.
