Hi @HaoyunJi,
Could you share what was the root cause or how you solved it? I'm experiencing the same problem.

I have a suspicion that it isn't directly related to the netshoot image specifically. When I am running it standalone it works just fine, I only get the kills when I'm using it as a k8s debug container. At first glance these kills seem to be related to memory, but there is plenty of resources on the node and the container I am running it next to has a very high limit. No namespace limits either.
Thanks!

I figured it out. Just in case someone finds this issue in the future, here's what the problem was.
It was the memory limit, unsurprisingly. I did set the it very high, but there was a VPA resource that overrode it with a much smaller value that I missed.
Launching the debug container with the --profile=sysadmin flag also helped me troubleshoot it as it allowed me to read the output of dmesg and confirm that it was indeed the OOMKiller that killed my processes.
