PI Heap memory issue

Hi,

When I try to take an export (R3load) for my PI 7.1 system, it terminates at the last step while exporting the Java schema @ table BC_MSG or BC_MSG_AUDIT  (sometimes) with an out of memory error.

I've got ample RAM & heap space assigned ..plus the message delete job runs daily..

pls. helpp.

Thank You,

Have a nice day,

Saba.
