I couldn't access worker nodes, but on a master node, the ps -elf indicated rmc had 10000 pages. That's ~640 MBs on mostly idle servers - master nodes. The failure above occurred on worker nodes, where ocs is deployed and I am running ocs-ci performance suite which deploys a bunch of fio pods...

The limit should be increased from 1 Gi to 1.5 or 2 Gi.

It could be that there is a memory leak in rmcd. @manojnkumar reported that after talking Myung Bae.
