Sure - send me the script. Like you say, sounds like you may be running into
some unexpected limit. Might help to zip it up first though.

My email's peter.hearty@lutris.com.

Regards

Pete

> Peter,

lines

> The script has 514 "INSERT INTO myTable VALUES(...)" lines.  If I remove
any of

exception.  I
