+Subject: [PATCH] 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.
