still trying to increase memory on the coral-dev board.
maybe memory limit on the dev-board is causing nginx-error ?? hoping to catch this without the help of others… but as a blind-man in the dark:

root@elusive-calf:/usr/src# ipcs -l

------ Messages Limits --------
max queues system wide = 32000
max size of message (bytes) = 8192
default max size of queue (bytes) = 16384

------ Shared Memory Limits --------
max number of segments = 4096
max seg size (kbytes) = 18014398509465599
max total shared memory (kbytes) = 18014398509481980
min seg size (bytes) = 1

------ Semaphore Limits --------
max number of arrays = 32000
max semaphores per array = 32000
max semaphores system wide = 1024000000
max ops per semop call = 500
semaphore max value = 32767

this works:

root@elusive-calf:/usr/src# docker run  docker.io/nginx:1.15.8
