What is the current behavior?

Both #327 and #378 have circleci test jobs being killed:

Server terminated abruptly (error code: 14, error message: '', log file: '/home/circleci/.cache/bazel/_bazel_circleci/cced162ff126e466524550c57f0d7df5/server/jvm.out')

According to the note in

rules_typescript/.circleci/bazel.rc

Lines 32 to 38 in 4a087c0

	# Since the default CircleCI container has only 4G, limiting the memory
	# is required to keep Bazel from exhausting the memory. These values
	# are determined experimentally. If the Bazel process crashes without
	# any error messages then the --local_resources and --host_jvm_args
	# memory should be reduced. If the Bazel process errors out within
	# a "JVM out of memory" error then the --host_jvm_args memory should
	# be increased.

this means the memory limit should be reduced.

What is the new behavior?

Lower memory limit.

@filipesilva If you rebase #378 and #327 to master they will get the xlarge resource_class in CircleCI for the test job and not run into memory issues anymore. This change isn't needed. I should probably remove the comment in .bazelrc as its based on trial and error not guaranteed to work in any case since the 4GB container was at the point with the test job that there may have been no memory configuration that would have allowed it to pass.
