After upgraded the kubernetes-plugin to 1.18.0, all of my pipelines hanging on in the one of shell step, and it ended up with the following error.
After a deep investigation, I've reproduced the issue with the following minimal pipeline code.
It hanging on in the last sh step inside of the `busybox` container.
and it works if I using the default `jnlp` container or by removing the `inheritFrom` from agent definition.
This is a major issue for running the pipelines using kubernetes plugin.
as the workaround, I've rollback to the version `1.17.3`, all works.
