Backup problem after upgrading to cPanel ver 84

[nickgr67]

Hello,

we are facing the following problem after updating to cPanel version 84 from version 82.

2 of our servers were updated to said version and they are unable to backup some sites hosted in these servers.
This problem seems to affect only some of the sites hosted in these servers (3/200 in one of them, 4/40 in the other) and has
been happening for two days straight (yesterday, today). Same sites both days.

We have many servers in our disposal, most running cPanel, and these are the only two that have displayed such a behavior
after the update to version 84 so we think these facts might be related.

We tried running the backup from the command line "/scripts/pkgacct theusername" to backup those sites but were unable to do so.
We also tried rebooting the servers which did not fix the issue.


Do you have any ideas as to what might be the problem or any possible solutions?


The server error logs are the following after running "/scripts/pkgacct theusername" (we have replaced the actual account username the word "theusername"):

I forgot to mention the fact that these two servers are in the current release tier (Release Candidate) while all our other servers are in the release release tier (General Availability).

I assume that this issue is not wide spread and is only affecting a few servers but it will become an issue once version 84 becomes "general availability"

I'm also seeing the same behavior after updating to cPanel 84, with only 1 account on 1 server, 2 nights in a row after updating to this version. Was this isolated to anything specific in the above cPanel ticket? Invoking pkgacct on the relevant account produces the same issue:

[2019-10-12 02:56:58 -0400] Creating Archive ....
ERROR: The subprocess “Archive::Tar::Builder” ended prematurely because it received the “ABRT” (6) signal. at /usr/local/cpanel/Cpanel/IO/Tarball.pm line 326.

Moderator note: removed full backtrace output.

This particular account was converted from an Addon Domain using the WHM functionality. There is nothing else unusual about it aside from perhaps the short username, and it's only ~2G in size on disk.

Actually in looking further back in the logs, this has only been occurring since updating to 84.0.1. There was one backup run on 84.0.0, and this account backed up fine at that time. So perhaps some regression in 84.0.1 specifically.

I have the same issue on one server, possibly two (in the process of checking second one now). No problems until after the servers updated to 11.84. Do I get to open a ticket as well ?

Same here. It's fine for all my accounts except one - which I would guess bears a relation to it being the largest (~5.5GB). The second largest account is ~4GB and packages fine.

In my case, on one server it's failing to back up an account because for whatever reason it can't do something with a mysql database during the pkgaccount stuff. On another account, there is some email in one of the directories of one of the email accounts on the server that is causing an Exception. That count doesn't get backed up either.

And, when even one account doesn't get backed up and all of the rest do, the pruning (daily/weekly/monthly) does not take place and the old backups just continue to sit on the backup until the backup fills up.

And all of this started happening with WHM 84.

This issue now appears to be resolved for me after WHM updated to v84.0.2. I should clarify in slight difference to the other posters that with me the issue was only present with v84.0.1 and not v84.0.0.
