[Spacewalk-list] Spacewalk Proxies failing to serve large packages

[Matthew Madey]

I'm seeing an issue with packages 300MB and larger being served by
Spacewalk proxies. When I run yum install on a client, it gets to 97% of
the download or so and fails with the below message:

Error Downloading Packages:
 somepackage.x86_64: failed to retrieve getPackage/somepackage.x86_64.rpm
from rhel-x86_64-server-6-datacenter
error was [Errno 14] PYCURL ERROR 18 - "transfer closed with 1499666 bytes
remaining to read"

Looking at the Spacewalk proxy, I see the below error:

[Fri May 08 18:42:28 2015] [error] [client 172.20.165.201] mod_wsgi
(pid=9403): Exception occurred processing WSGI script
'/usr/share/rhn/wsgi/xmlrpc.py'.
[Fri May 08 18:42:28 2015] [error] [client 172.20.165.201] IOError: failed
to write data

Here's what I've tried so far with no luck:

1. Increase max_object_size parameter in squid.conf to 500MB
2. Turn on KeepAlive parameter in httpd.conf
3. Increase KeepAlive timeout in httpd.conf to 120 seconds
4. Increase Timeout in httpd.conf to 120 seconds

Any ideas?
