Hi Amarnath,

interesting problem. I think we'd need to see more data to get somewhere though.

Is there a possibility that you have some kind of caching proxy in between your host and the httpd repo?

https://access.redhat.com/solutions/316813 discusses this in terms of RHN Proxy, but this is a little bit of a shot in the dark at the moment.

can you get the relevant section of the log from the httpd server and see if we can build up a picture of what both sides of the equation were doing at the time?

one interesting test would be to drop the --range argument to curl, get the whole RPM and then check its cksum.

Checksums are found on the individual rpm package page: nss-pam-ldapd-0.7.5-14.el6_2.1.x86_64.rpm

let us know,
Mark

Hi Mark,

Thank you for your swift response.

I did check the PROXY solution and since there were no rpms downloaded /var/cache directory. One different I missed out to mention is I am using an svn server's mod_dav_svn.so in httpd to download the rpms.

I tried the curl without --range and checked the sha256sum on the downloaded rpm the checksum matched with Redhat checksum.

Hi Amarnath,

I have found this upstream which appears to match the problem: http://svn.haxx.se/dev/archive-2009-08/0274.shtml.

I have been unable to find any records in kbase, Bugzilla, or customer tickets that match either the upstream report or the errors you describe (at least not outside of rhn-proxy).

Assuming the httpd server is running on RHEL, are you able to open a ticket please? I think this needs to be investigated further through the support channels.

Sorry we can't fix it here,
Mark

Hi Mark,

Thanks for the pointers. I noticed apache DOS's such as file, disk and mem cache are enabled, but not deflate. On retry I see httpd memory beefing up and suddenly dropping and the corresponding error log indicates that anaconda suddenly terminating the remote connection.

Anyway, due to time constraint I have resolved to cdrom based installation and later updating packages during %post install from the SVN. One last question though on checksum, is the checksum(sha256) is validated against the primary.sqlite3.bz2 or with rpm headers?

Many thanks for your help.

Regards,
Amarnath.
