Hi Peter,

How much memory do you have on that PC? You nay try to limit the size of VFP buffer memory with SYS(3050).

>Sadly enough, the flushing with FFLUSH() hasn't helped in any way. The same error 1150 still occurs at the same moment, in my case after the processing of more than 9 million records/lines. There must be something else causing the trouble.
