YangZhou1997 commented on issue #4476: how to remove concurrency limits URL: https://github.com/apache/incubator-openwhisk/issues/4476#issuecomment-491664067 It seems that I cannot directly set the memory to 163840m, since the CPU-share would become lower than 2 and cause container creation crash. Please see the log from invoker: ` [2019-05-13T02:46:09.470Z] [INFO] [#tid_437421f4eeb8e1fc5465be9581c85978] [DockerClientWithFileAccess] running /usr/bin/docker run -d --cpu-shares 1 --memory 256m --memory-swap 256m --network openwhiskOverlay -e __OW_API_HOST=https://10.10.1.2:443 --name wsk33_40_whisksystem_fib --pids-limit 1024 --cap-drop NET_RAW --cap-drop NET_ADMIN --ulimit nofile=1024:1024 --log-driver json-file --env __OW_ALLOW_CONCURRENT=True yangzhou1997/python3action:mpi (timeout: 1 minute) [marker:invoker_docker.run_start:8473] [2019-05-13T02:46:11.681Z] [ERROR] [#tid_437421f4eeb8e1fc5465be9581c85978] [DockerClientWithFileAccess] info: command was unsuccessful, code: 125 (unsuccessful), stdout: a115e5b3be467aa7ea1181111b00dcfe1b8ec8770af2cca58a3afb23dc39347f, stderr: WARNING: Your kernel does not support swap limit capabilities or the cgroup is not mounted.

[marker:invoker_docker.run_error:10684:2210] ` 40960m is a workable number I have tried, which, however, reduces the maximum memory capacity of my machine four times. I am further wondering if there is a feasible solution to solve this dilemma.
