dbi error -919 ; RDM Embedded DB err or System/OS error

Cloverleaf ver 5.6 rev 2 on AIX 5.3

while putting load onto the server, the processes handling the load died with the below error in the process log :

[dbi :dbi :ERR /0:     la_xlate:05/20/2009 15:36:22] (-919) ‘RDM Embedded DB err

or: “SYSTEM/OS error: -919

error writing to a data or key file

C errno = 0: Error 0″

‘

which data or key file is Cloverleaf referring to  ? Anyone got this error before and any suggestion how to resolve it ?

Thanks

checking thru the database directory, none on the files even come close to the 2GB limitation :

CGCLPS01:/qvdx/qdx5.6/integrator/testcg/exec/databases>ls -lrt
