Check_MK Werk 6860: Fixed random backup issues: "Connection reset by peer"

ID: 6860 Title: Fixed random backup issues: "Connection reset by peer" Component: Site Management Level: 1 Class: Bug fix Version: 1.6.0i1 The "mkbackup" and "omd backup" commands could fail while backing up a site when the rrdcached process was reloaded, restarted or stopped during the backup. This could also be triggered by an "Activate changes" action in the GUI. The backup was then aborted with an error like this: "Failed to perform backup: [Errno 104] Connection reset by peer". This issue did not affect backups performed for not running sites.
