Sorry for missing the information in above statement. In above experiment,
the memory.limit_in_bytes has also been set to same quota as memory.
max_usage_in_bytes. In other words,

# cat mycontainer/memory.limit_in_bytes
3002368
# cat mycontainer/memory.max_usage_in_bytes
3002368


Under these setting, I got the result as mentioned in last email.

Any help?



Best,
