Hi,
during sync of the EPEL repos from below I get:
[Errno 24] Too many open files

This can't be true because I see <600 open files during download and in limits.conf I have:

• hard nofile 500000
• soft nofile 500000

Thew repos to be downloaded:
https://dl.fedoraproject.org/pub/epel/7/x86_64/
https://dl.fedoraproject.org/pub/epel/8/Everything/x86_64/

Currently installed are the latest rpm's on Centos8:
