RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Fixed In Version: abrt-2.0.8-36.el6
Doc Type: Bug Fix
Doc Text:
_abrt_ no longer missing a dependency on _python-argparse_ A previously missing dependency of the _abrt_ packages on the _python-argparse_ package resulting in errors like "ImportError: No module named argparse" has been fixed. This problem usually occurred if customers upgraded from an earlier version of Red Hat Enterprise Linux, or during a fresh installation if customers removed the _nfs-utils_ or _ipa-client_ packages.

Description James Boyle 2015-07-24 14:13:24 UTC
Description of problem:
abrt-dump-oops produces a prodigious number of error emails because /usr/libexec/abrt-action-generate-machine-id crashes (see below).  This behavior began to occur follow automatic updates were applied through yum cron. 

Version-Release number of selected component (if applicable):
abrt-2.0.8-34.el6.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Allow abrtd to run and eventually launch abrt-dump-oops
2.
3.

Actual results:
abrt components repeatedly crash when processing the queue and a large number of email notifications are sent (see below).

Approximately 2100 emails were generated within 6 hours because abrt-dump-oops did not detect that it continued to fail to process the /var/spool/abrt queue.

Expected results:
/usr/libexec/abrt-action-generate-machine-id should run properly.


Additional info:
abrt_version:   2.0.8
cmdline:        /usr/bin/python /usr/libexec/abrt-action-generate-machine-id -o /var/spool/abrt/pyhook-2015-07-24-03:26:29-13226/machineid

Comment 2 Jakub Filak 2015-07-27 14:36:44 UTC
Thank you for the report!

abrt-action-generate-machine-id crashes because abrt package misses a dependency on python-argparse. abrt-dump-oops triggers abrt-action-generate-machine-id, therefore I think that abrt-dump-oops runs continuously for some other reason.

Please install that package:
# yum install python-argparse

and run the following command:
# /usr/libexec/abrt-action-generate-machine-id

to verify that the crash is fixed.

Please attach the result of the following command as well:
# cat /var/log/messages | grep abrt

Comment 3 James Boyle 2015-07-28 01:45:23 UTC
Installing python-argparse fixes the error, but why was the dependency not installed in the first place?  

I can verify the /usr/libexec/abrt-action-generate-machine-id works and returns info from dmidecode.

grep abrt /var/log/messages is far too long to list entirely, but here is a sample:

Because I forgot to add "Requires: python-argparse" to abrt's spec file.

What type of installation did you chose? I installed RHEL-6.7 Workstation on my VM and python-argparse was pulled in as a dependency of nfs-utils and ipa-client.

/var/log/messages lines look ok. How did you find out that abrt-dump-oops runs continuously?

Honestly - this makes me feel better!  I didn't want to have to consider other possibilities of why the package might not have been there (other admin, intrusion, etc.). :^)

This was a server installation from RHEL 6.5 (or earlier) that has been patched to current along the way.  It aims to be FISMA compliant and in line with that, the general rule is to have the bare minimum installed that's required to get the job done.  (things like nfs are not installed at all on this system)

'ps auxwww |grep abrt' showed me that abrt-dump-oops is/was running.  Maybe it's supposed to be running all the time (looking at some other systems now, I'm sure it was supposed to be).  I could have stated my issue better as, given previous conditions, it seems like a race condition: [scan spool for crashes] -> [crash yourself trying to make the report] -> [email] -> [repeat] ...  Anyway, my biggest issue was that my inbox was flooded.

I appreciate your help!
Thank you,
--James

Comment 6 Kodiak Firesmith 2015-07-31 15:31:45 UTC
I also noticed the missing dep on a minimal server install in my infra as well - after seeing 9k traceback emails in root mail.  

I'll be filing a support ticket with Red Hat support services to see about getting a new version of this released asap.  In the mean time I'll add python-argparse to our server baseline via Puppet.

So the issue has started appearing after you upgraded to RHEL-6.7

Your assumptions is correct, abrt-dump-oops watches /var/log/messages for kernel stack traces and converts them to ABRT problem records.

Comment 16 James Boyle 2016-02-26 19:01:12 UTC
It is important to note that users could have also experienced this issue from a fresh installation if they removed nfs-utils or ipa-client.  In some environments and compliance situations only the absolute bare minimum of installed software is allowed, so administrators will remove nfs-utils if the system is not expected to mount NFS volumes.
