Checkmk Werk 10070: systemd: Fixed possible memory leak related to KillMode in unit file

by Ronny Bruska

ID: 10070 Title: systemd: Fixed possible memory leak related to KillMode in unit file Component: Checks & agents Level: 1 Class: Bug fix Version: 1.7.0i1 We have seen cases in which the parameter "KillMode=process" of the unit file "check_mk@.service" causes a memory leak. This was first seen on Debian Buster but could occur in the future on other operating systems too. The cached check runs that are forked in the backround seem to cause systemd not to discard the service once it's done. If you run: C+: RP:systemd-cgls -au system-check_mk.slice C-: you can see a lot of old services and task_struct objects in slab growing constantly. You can see those processes also on eg. Debian Stretch but there they should have no effect on task_struct objects. To fix this, the parameter "KillMode=process" was changed to "Type=forking". To change the unit file: C+: RP:systemctl stop check_mk.socket RP:systemctl disable check_mk.socket C-: Copy the new check_mk@.service unit file to /etc/systemd/system/. You can download the file within "Monitoring Agents" - "Agent files" or find it in site user context ~/share/check_mk/agents/cfg_examples/systemd/. C+: RP:systemctl daemon-reload RP:systemctl enable check_mk.socket RP:systemctl start check_mk.socket C-:

Checkmk Werk 10179: Discovery page: Missing "full scan" button in some cases

by Lars Michelsen

ID: 10179 Title: Discovery page: Missing "full scan" button in some cases Component: WATO Level: 1 Class: Bug fix Version: 1.7.0i1 In previous 1.6 releases the message "No discovery information available. Please perform a full scan." could appear without a visible "Full scan" button could appear making it hard to proceed with a service discovery. As a workaround with previou versions, you could execute a bulk discovery for this host or go on the diagnostic page and click on the "Test" button once. Afterwards you should be able to proceed on the discovery page.
