Hi again Reydp.

This issue was a one of. There have been no repeat incidents since last week and the process has been run several times.

No parameters changes have been made because of this.

I guess what I was really hoping for was some suggestions as to what *could* cause the process to suddenly run out of memory when it has never done so before or since.

Whilst I appreciate Tamil's response, I understand the message and what parameters could be changed to correct it if it were an on going problem. However if the problem can't be replicated (believe me I've tried) then the "solution" cannot be proven to have worked and the original suggested cause cannot be disproven.

I suspect I'll have to wait and see if there is another failure

Until next time....

Nick
