Hi All,
I was able to download cronie patchlevel 10 from CentOS Stream and found
2 additional patches that are not included in AlmaLinux 8:
1) 0004-Fix-regression-in-handling-1-5-crontab-entries.patch
2) optimization_to_close_fds.patch (which is another approach to fix
100% CPU usage bug):

The problem is important, prevents from using cronjobs.
Nobody answers here and in the chat, no way to set up a ticket, patches
from CentOS are not included. Is AlmaLinux supported at all?
