Limited the memory used by the client by adding this to my server config:

client {
  memory_total_mb = 2000
}

Generated test jobs:

./generate.sh baz 10 1000 600

FEATURES:

• scheduler: Enable deployments for system jobs [GH-26708]
• secrets: Adds secret block for fetching and interpolating secrets in job spec [GH-26681]

BREAKING CHANGES:

• metrics: Eval broker metrics that previously used the job ID as a label will now use the parent ID of dispatch and periodic jobs [GH-26737]
• sysbatch: Submitting a sysbatch job with a reschedule block will now return an error instead of being silently ignored [GH-26279]

# There can only be a single job definition per file. This job is named
# "example" so it will create a job with the ID and Name "example".

# The "job" block is the top-most configuration option in the job
# specification. A job is a declarative specification of tasks that Nomad
# should run. Jobs have a globally unique name, one or many task groups, which
# are themselves collections of one or many tasks.
#
# For more information and examples on the "job" block, please see
# the online documentation at:
