[ClusterLabs] PCSD - High Memory Usage

I'm running a cluster with 9 active nodes (4 in standby), on this cluster are 258 registered resources. 99% of these are perl and java process ran via multi-target systemd units, 2 are heartbeat IPaddr2 and 1 fence device. I am seeing very high memory usage in the pcsd process, 2.5GB to 2.7GB on most node with one running 3.3GB.

Is this kind of memory usage to be expected when managing this volume of resources? I am running pacemaker version 1.1.19 on CentOS7.6.1810.

Any suggestions or advice is greatly appreciated.
