Processes are crashes which are running inside the docker container by OS

i am using IBM websphere product which are running inside the docker container. docker is installed on the EC2 machine. there are 6 containers running on the EC2. OS is killing one pid and with this PID 2-3 docker processes are going which are not connected to that PID.

can anyone tell how to get PID mapping of host to container.

kernel: Killed process 4043 (java) total-vm:5056296kB, anon-rss:3169364kB, file-rss:0kB, shmem-rss:124kB
