Subject: Drop any systemd imposed process/thread limits
X-Git-Tag: v10.1.2~47^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=05cafcf19fb80dd2a76fdbbe5329bae53aa0def4;p=ceph.git

Drop any systemd imposed process/thread limits

If systemd has task accounting enabled, a default of 512 tasks
will be applied to all systemd units.

For ceph, this is way to low even for a modest cluster, so stop
this restriction being applied and allow administrators to apply
limits using sysctl.
