+h3(#ReserveExtraRAM). ReserveExtraRAM: Extra RAM for jobs
+
+Extra RAM to reserve (in bytes) on each SLURM job submitted by Arvados, which is added to the amount specified in the container's @runtime_constraints@. If not provided, the default value is zero. Helpful when using @-cgroup-parent-subsystem@, where @crunch-run@ and @arv-mount@ share the control group memory limit with the user process. In this situation, at least 256MiB is recommended to accomodate each container's @crunch-run@ and @arv-mount@ processes.
