Package: network-manager Version: 1.6.2-3+deb9u2 Severity: important Tags: patch
Description of problem: NetworkManager is consuming hugh memory when dhclient invoke nm-dhcp-wrapper. How to reproduce: To repoduce the issue you have to call a dhclient in the loop to simulate dhcp events: dhclient -q -sf /usr/lib/NetworkManager/nm-dhcp-helper -pf /var/run/<dhclient.pid> -lf /var/lib/NetworkManager/<dhclient.lease> Actual results: The amount of memory consumed by NetworkManager increases during a short period of time during handling dhcp events by NetworkManager. Expected results: Memory usage of NetworkManager should not increased on dhcp events.
