There is a bug [1] describing the problem with creating a diagnostic snapshot. The issue is that /var/log has 100GB available, while /var (where diagnostic snapshot is being generated - /var/www/nailgun/dump/fuel-snapshot according to [2]) has 10GB available, so dumping the logs can be an issue when logs size exceed free space in /var.</div><div><br></div><div>There are several things we could do, but I am unsure on which course to take.
