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.

Steps to Reproduce:
1.
2.
3.

Actual results:

Networkmanager is consuming high memory.


Expected results:

Memory consumption should be normal.

Additional info:

updated the atomic host version from  7.3.2 to 7.3.4-1 for getting the latest NM package but the issue still persists.

Hi,

I think this is a different issue than bug 1436650, because that was
reported as fixed by other users.

Maybe you can try to run NM under valgrind for some time (at least 20
minutes), then kill it with Control-C and attach the log.txt
file? Here the steps:

 yum install valgrind
 systemctl stop NetworkManager
 valgrind --leak-check=full /sbin/NetworkManager -d > log.txt 2>&1
 # (... kill it after some time)
 systemctl start NetworkManager

Thanks!

From the customer case comments I understand that the leak only
happens on some machines and not on others. Do you have any idea about
the differences in configuration between those?

The attached valgrind log doesn't show any evident memory leak. I also
tried to reproduce the scenario in a VM where ovs slaves are
constantly added and removed, but I see a constant memory usage.

Would you mind doing another try with the following commands, which
should capture also the memory blocks that are still reachable and
will show more information about what NM is doing?

 systemctl mask NetworkManager
 systemctl stop NetworkManager
 valgrind --leak-check=full --show-leak-kinds=all --num-callers=40 /sbin/NetworkManager -d --log-level=TRACE > log.txt 2>&1
 # Wait 15 minutes, then terminate with Ctrl-C

Thanks!
