You have two options:
#,,Reduce the volume of data in BWA: Delete BWA indexes that you do not
really need at the moment.
#,,Contact your BWA hardware partner and resize the BWA hardware.

Procedure for System Administrators

In the standard setting, this message only appears as a warning in
processes that index large volumes of data to BWA. You can use ad
ministration parameters to set it as an error message instead. This
causes all index processes to terminate if the error occurs.
To do this, run program RSDDTREX_ADMIN_MAINTAIN with parameters Object=
DONT_IGNORE_BIA_OVERLOAD, Value = X, and INSERT/UPDATE = X.
