Hello,

When a customer does a large order, it seems the webshop runs out of memory. Currently the PHP memory_limit is set to 1GB (which is pretty large) and still the webshop occasionally runs out of memory. A large order is about 20-30 different products of about 10 different vendors (creating sub-orders for each vendor with Hikamarket).

The hosting has about 6 out of 8 GB available - so that should not be a problem.

When this error occurs, the parent order is created with the relevant products, but for each item/vendor the sub-order is not created and have to be added manually to correct the order.

Is this a webhosting issue, or is the Hikashop / Hikamarket checkout eating alot of memory when large orders come along?

Cheers,
Teeuwis

Checking other plugins got us on the right track.

We have a plugin who appends extra info to the order history with the trigger after the order is saved. It basically checks what has changed between the old order and the new order and logs this in the order history. I can imagine that will clog up allot of memory when it is triggered with each sub-order due to Hikamarket.

I have now disabled that plugin and we'll see how the memory consumption is coming days. Thanks for the tip!
