Ошибка субд cannot allocate memory for output buffer

Hi

So I was developing a module that exports every products barcode and image to an Excel, and that then returns the an Excel file. This works fine when there’s just a couple pictures, but when I tried running the method on a bigger db with tons more pictures I got an error.

Here is the code that’s being run:

Here is the traceback:

Fout:
Odoo Server Error

During handling of the above exception, another exception occurred:

MemoryError

Anyone know how I could solve this?

For those wondering, these are in my config file:

limit_memory_hard = 2684354560
limit_memory_soft = 2147483648
limit_request = 8192
limit_time_cpu = 120
limit_time_real = 9999
limit_time_real_cron = -1
longpolling_port = 8072
max_cron_threads = 9
workers = 0

When I put more then 0 workers, I get a bus error so that’s another problem.
