Increase the number of possible child processes
The mirrorlist-server is the process which has the mirrorlist data
loaded and which is accessed by the public facing
mirrorlist_client.wsgi. The mirrorlist-server uses the
ForkingUnixStreamServer which has a default of max_children = 40.
(https://hg.python.org/cpython/file/2.7/Lib/SocketServer.py#l516)
Looking at the code of ForkingUnixStreamServer it says at
https://hg.python.org/cpython/file/2.7/Lib/SocketServer.py#l523
# If we're above the max number of children, wait and reap them until
# we go back below threshold. Note that we use waitpid(-1) below to be
# able to collect children in size(<defunct children>) syscalls instead
# of size(<children>): the downside is that this might reap children
# which we didn't spawn, which is why we only resort to this when we're
# above max_children.
As we are running the wsgi with processes=45 this sounds like it can
lead to situation where it might just hang.
This increases max_children to 80 and processes to 60.
