Yes, i my case, i was converting 280.000 records in 8 batches, and each batch approx wil take 11 hours.
But i soon discovered that (while the garbled error came up) i had to chunk the batches into 3 hours, and then it went well.
So i was forced to activate 32 batches AFTER each other, and it seems that, if the executable stopped and started, the error kept away.
On Marcus advice , i recompile the script, but i'm now about 99 precent sure, that i allready compiled it with the latest version....
I got the error on 18 juli 2010 9:36
and I updated to 12.05 on 12 juli 12:10 and the script was compiled 15 juli 20:00
Wel ok, i recompile everything, and next time , i try the 11 hour trip, we ll see what happens...

by the way: i noticed a tremendous speed decrease after processing 10.000 records, so I suspected a kind of memory leak.
