Foreman » Smart Proxy

Linked BZ describes a side effect of async downloads:

i been able to reliably reproduce this now and I believe what triggers this is assigning a 2nd host to a host group before the vmlinuz/initrd download has finished from the first host to host group assignment.

according to the foreman-proxy.log, the 2nd assignment causes an additional background task to get started to download the files. You then have multiple downloads clobbering each other.

likewise for any subsequent assignment if there is already a download running.

I've attached my foreman-proxy.log. It doesn't show anything different really from a successful download, but you can at least see it starting an additional download task before the first has even finished.

I end up with files that are much larger than they should be:

[root@staypuft boot]# pwd
/var/lib/tftpboot/boot
[root@staypuft boot]# ll -h
total 277M
