@mousepad got any solution for this ?
Hello @mousepad
Check server log for same.
just check error log or read core dump file
Nothing in the error log but where would I find the core dump file ?
No. Looks like it's a common bug but I have not been able to upgrade. I think it has to do with my data that was converted from 1.9.x a long time ago.
Hi Mousepad,
I've just had the same issue and finally worked out a fix,
the crash is coming from the upgrade failing to fill the quote_address_id in table sales_order_address - I solved it by entering a value into every row (I just put 100 in every one).
It isn't the most correct of fixes but it's allowed the update to complete and as far as I can see Magento is working correctly!
There's now a proper fix for this issue here
