I developed a php script that allows to import accounting entries from an excel file, in odoo 8, via xmlrpc, with the ripcord library. It works very well for sales, cash, and payroll. 

But when I start the purchase file, after inserting 368 lines, the program stops. The same for the bank entries, after 600 lines the program stops. I looked in the logs but I didn't see any error.

 However the sales are 2000 lines long, and it works. Please help me.

 Is there another way to see the logs for the xmlrpc?
