Hello,
According to this link:  https://github.com/wkhtmltopdf/wkhtmltopdf/issues/4957 [1] , you can resolved this issue by increase
file and stack limits with command: "ulimit -n 10000".

I had the same problem, I have solved it for some time by increasing the number of workers in my configuration then I faced the same issue with huge datasets.
For this, I have solved the issue by adding queue_job module from OCA.
I hope this helps!
