Kubernetes Process Name Error

[zzhzero]

Describe the bug

process.name != readfile(/proc/{pid}/comm)

To Reproduce The original code cannot be provided

I tried the following logic,It's not real code :

p = newProcess(pid)
print(p.Name()) //out: a-b-docker

conn= ReadFile(/proc/{pid}/comm)
printf(string(conn)) //out: a-b-do

The two outputs are inconsistent

I try to execute ps -e |grep {pid} // out: a-b-do The result is the same as comm

Environment:

Centos 7

The process is managed by kubernetes

I try to execute the test code on the machine where the process is located
