Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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.

Description of problem:
 * sediff gets killed by OOM killer when --allow or --dontaudit or --stats parameter is used

Version-Release number of selected component (if applicable):
setools-console-3.3.8-1.el7.x86_64

How reproducible:
always

Steps to Reproduce:
# sediff --allow /etc/selinux/targeted/policy/policy.29 \; /etc/selinux/targeted/policy/policy.30 
Killed
# echo $?
137
# dmesg | tail -n 2
[ 4033.789560] Out of memory: Kill process 5430 (sediff) score 672 or sacrifice child
[ 4033.789561] Killed process 5430 (sediff) total-vm:1360016kB, anon-rss:569884kB, file-rss:0kB
#

Actual results:
 * sediff is killed by OOM killer because it consumed too much memory

Expected results:
 * sediff works as expected and terminates correctly

sediff finished on a ppc64 machine equipped by 16GB RAM. The peak of memory allocated by the sediff process in about 7GB.

I'm not sure we can do it for RHEL-7.3. It would need an upstream patch while setools3 is considered mature and should be obsoleted soon by setools4.

As a workaround, if you need to do memory demanding operations, just raise amount of memory attached to your VMs.
