Also, adding stork-focused email distro, though I suspect the membership is largely overlapping 😊

And no, I have not done anything to the processes, not even restarted them over the course of a last week or so. I looked through the logs and I do not see any explanation for the behavior. Node1 is where I constantly change the config (it is the lab after all) and the process is restarted over and over again (“service xxx restart” from shell) but even there I would not expect a process hanging for any reason Marek From: Darren Ankney <darren.ank...@gmail.com <mailto:darren.ank...@gmail.com> > Sent: Tuesday, May 14, 2024 5:28 AM To: mxhajducze...@gmail.com <mailto:mxhajducze...@gmail.com> ; Kea user's list <kea-users@lists.isc.org <mailto:kea-users@lists.isc.org> > Subject: Re: [Kea-users] High memory utilization for Kea server / Stork agent Hi Marek, It appears that kea-dhcp4. kea-dhcp6, and stork-agent were started multiple times. I do not know how you are starting the daemons but perhaps something changed with the startup process (systemd?) that caused the thing that is starting the daemons to not realize they are running, thusly starting them multiple times?

I seem to be running multiple copies of processes for some reason, with stork-agent likely being the primary culprit, and Kea DHCP servers being likely the second culprit. I have the very same situation on both lab nodes. I have to restart the server / stork agent periodically to eliminate the memory bloat. 634 stork-age 20 0 1866M 26240 15824 S 0.0 0.3 7:35.77 /usr/bin/stork-agent 709 stork-age 20 0 1866M 26240 15824 S 0.0 0.3 0:18.34 /usr/bin/stork-agent 710 stork-age 20 0 1866M 26240 15824 S 0.0 0.3 0:34.27 /usr/bin/stork-agent 711 stork-age 20 0 1866M 26240 15824 S 0.0 0.3 0:00.00 /usr/bin/stork-agent 713 stork-age 20 0 1866M 26240 15824 S 0.0 0.3 0:00.01 /usr/bin/stork-agent 727 stork-age 20 0 1866M 26240 15824 S 0.0 0.3 0:00.00 /usr/bin/stork-agent 740 stork-age 20 0 1866M 26240 15824 S 0.0 0.3 1:29.63 /usr/bin/stork-agent 894 stork-age 20 0 1866M 26240 15824 S 0.0 0.3 1:24.96 /usr/bin/stork-agent 1921 stork-age 20 0 1866M 26240 15824 S 0.0 0.3 1:29.49 /usr/bin/stork-agent 15986 stork-age 20 0 1866M 26240 15824 S 0.0 0.3 0:53.26 /usr/bin/stork-agent 1340 _kea 20 0 507M 23864 16784 S 0.0 0.3 4:54.19 /usr/sbin/kea-dhcp6 -c /etc/kea/kea-dhcp6.conf 1341 _kea 20 0 507M 23864 16784 S 0.0 0.3 0:00.00 /usr/sbin/kea-dhcp6 -c /etc/kea/kea-dhcp6.conf 1342 _kea 20 0 507M 23864 16784 S 0.0 0.3 0:00.00 /usr/sbin/kea-dhcp6 -c /etc/kea/kea-dhcp6.conf 1343 _kea 20 0 507M 23864 16784 S 0.0 0.3 0:00.00 /usr/sbin/kea-dhcp6 -c /etc/kea/kea-dhcp6.conf 1344 _kea 20 0 507M 23864 16784 S 0.0 0.3 0:00.00 /usr/sbin/kea-dhcp6 -c /etc/kea/kea-dhcp6.conf 1352 _kea 20 0 507M 23864 16784 S 0.0 0.3 0:05.43 /usr/sbin/kea-dhcp6 -c /etc/kea/kea-dhcp6.conf 1353 _kea 20 0 507M 23864 16784 S 0.0 0.3 0:05.49 /usr/sbin/kea-dhcp6 -c /etc/kea/kea-dhcp6.conf 1354 _kea 20 0 507M 23864 16784 S 0.0 0.3 0:08.22 /usr/sbin/kea-dhcp6 -c /etc/kea/kea-dhcp6.conf 1355 _kea 20 0 507M 23864 16784 S 0.0 0.3 0:08.25 /usr/sbin/kea-dhcp6 -c /etc/kea/kea-dhcp6.conf 20544 _kea 20 0 507M 23864 16784 S 0.0 0.3 0:00.00 /usr/sbin/kea-dhcp6 -c /etc/kea/kea-dhcp6.conf 20545 _kea 20 0 507M 23864 16784 S 0.0 0.3 0:00.00 /usr/sbin/kea-dhcp6 -c /etc/kea/kea-dhcp6.conf 679 root 20 0 107M 20736 12596 S 0.0 0.3 0:00.04 /usr/bin/python3 /usr/share/unattended-upgrades/unattended-upgrade-shutdown --wait-for-signal 732 root 20 0 107M 20736 12596 S 0.0 0.3 0:00.00 /usr/bin/python3 /usr/share/unattended-upgrades/unattended-upgrade-shutdown --wait-for-signal 1889 _kea 20 0 507M 19292 14552 S 0.0 0.2 3:05.41 /usr/sbin/kea-dhcp4 -c /etc/kea/kea-dhcp4.conf 1890 _kea 20 0 507M 19292 14552 S 0.0 0.2 0:00.00 /usr/sbin/kea-dhcp4 -c /etc/kea/kea-dhcp4.conf 1891 _kea 20 0 507M 19292 14552 S 0.0 0.2 0:00.00 /usr/sbin/kea-dhcp4 -c /etc/kea/kea-dhcp4.conf 1892 _kea 20 0 507M 19292 14552 S 0.0 0.2 0:00.00 /usr/sbin/kea-dhcp4 -c /etc/kea/kea-dhcp4.conf 1893 _kea 20 0 507M 19292 14552 S 0.0 0.2 0:00.00 /usr/sbin/kea-dhcp4 -c /etc/kea/kea-dhcp4.conf 1897 _kea 20 0 507M 19292 14552 S 0.0 0.2 0:05.47 /usr/sbin/kea-dhcp4 -c /etc/kea/kea-dhcp4.conf 1898 _kea 20 0 507M 19292 14552 S 0.0 0.2 0:05.15 /usr/sbin/kea-dhcp4 -c /etc/kea/kea-dhcp4.conf 1899 _kea 20 0 507M 19292 14552 S 0.0 0.2 0:10.02 /usr/sbin/kea-dhcp4 -c /etc/kea/kea-dhcp4.conf 1900 _kea 20 0 507M 19292 14552 S 0.0 0.2 0:09.95 /usr/sbin/kea-dhcp4 -c /etc/kea/kea-dhcp4.conf 20586 _kea 20 0 507M 19292 14552 S 0.0 0.2 0:00.09 /usr/sbin/kea-dhcp4 -c /etc/kea/kea-dhcp4.conf 20587 _kea 20 0 507M 19292 14552 S 0.0 0.2 0:00.08 /usr/sbin/kea-dhcp4 -c /etc/kea/kea-dhcp4.conf Regards Marek -- ISC funds the development of this software with paid support subscriptions.
