cpanel/perl/YAML/Syck.pm error blocking backups

[ericmars]

Hello, I am running a VPS with the following spec:

CENTOS 6.5 i686 virtuozzo – server WHM 11.40.0 (build 26)

My VPS was set to automatically update, and therefore last week, updated to the latest version which then caused my VPS to become inaccessible. The hosting company informed me that this was due to the issue described here:
OpenVZ - RHEL/CentOS/Scientific 6.5 Container Networking Bug - Hosting Security and Technology - Web Hosting Talk

They have since disabled updates and followed the instructions on that thread. My sites are back online now and I have access to WHM.

However, my backups are failing now, and I am getting an empty log report. From within cPanel, when I attempt to adjust the backup config (new backup, not legacy), I am being given this errror message:

[a fatal error or timeout occurred while processing this directive]

Clicking this error gives further information as follows:

Syck parser (line 14, column -1): syntax error at /usr/local/cpanel/perl/YAML/Syck.pm line 78, <$fh> line 1.
YAML::Syck::Load() called at /usr/local/cpanel/perl/YAML/Syck.pm line 127
YAML::Syck::LoadFile('/var/cpanel/backups/SocialSlot_UID_03BOl7XX6cWUOM5VNlMy3rNz.back...') called at /usr/local/cpanel/Cpanel/Backup/Transport.pm line 378

My hosting company has told me that supporting this is beyond their scope and they have advised me to post in here. I am an intermediate user, so I would very much appreciate some hand-holding in resolving this issue. E.g. what steps I need to take to provide you with more information so I can have this resolved.

Many thanks in advance for your time.
Eric

Hello

Please try forcing an update of cPanel via:

/scripts/upcp --force

If the issue persists, let us know the output to /usr/local/cpanel/logs/error_log that occurs when browsing the backup configuration area.

Thank you.

An hour ago, my hosting provider responded with the following summary:


As far as I can tell, our NOC installed iproute from the CentOS 6.4 image, /root/iproute-2.6.32-23.el6.i686.rpm and then excluded this file from updating through YUM. Other than that I don't see any indication of other changes we have made to your server. I attempted to force cPanel to update hoping it would fix whatever is causing this to happen, but it did not help.****

Which would lead me to believe they already did this.


I will attempt to post the contents of the error log at /usr/local/cpanel/logs/error_log in a short while.

Thank you.

Remember to only post the snippet from the error log associated with browsing to the backup configuration page in WHM. The entire error log is not necessary.

Thank you.

Thanks for that... ok, I have now clicked on backups and then on the error itself, (so I saw the same Syck.pm error visually again) and then I took a look at the error_log file, and this seems to be the relevant notes:
