[Solved] OCI runtime create failed: container_linux.go:348: starting container process caused "process_linux.go:301: running exec setns process for init caused \"exit status 40\"": unknown

 Problem:- OCI runtime create failed: container_linux.go:348: starting container process caused "process_linux.go:301: running exec setns process for init caused \"exit status 40\"": unknown

Solution:-

This problem can occur when too much memory is used in cache, running echo 1 > /proc/sys/vm/drop_caches should solve the problem. It will clear the pagecache only.
