Duplicate orders caused by OSC module

Hi All,

I’m debugging an issue currently that has been plaguing one of our clients site now for a good few months. I’m not a massive fan of OSC modules but our client insists on using it.

The client processes around 1000 orders a day and about 10% of these orders customers report that they did not see the ‘Thank you your order page’ and instead were sent to the empty basket page.

We don’t usually experience this when testing changes on the development site but then I’m not sure we ever reach the volume of orders the live website does.

Has anyone ever experienced this issue? I feel it has to be related to Redis in some way but I’ve tried enable/disable locking and increasing frontend limits which doesn’t seem to help.
