Looking at the historic utilization over the week
you can clearly see a rather dramatic increase in memory utilization starting 5/10, with no specific changes to what the node is doing.

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
