We have a k8s cluster, using Kasten K10 to backup those workloads, has a k10 sidecar “attached” to each workload.

Recently we found that the Linux OS of the worker nodes frequently has some <defunct> processes, with keyword “chrome”.

Our support team (who manages and operates the k8s cluster) says they asked K10 support team, who told them these processes were caused by K10 software, a bug that will be fixed in future.

I am kind of new to all these k8s, k10 things. This makes me very confused. Does K10 use Google Chrome browser internally?? Or the word “chrome” has any other special meaning in K10, or in k8s, or in general Linux system??

I tried to google about it, but the Google Chrome browser is so dominating in the world, that almost all search results about the word “chrome” are referring to Google Chrome browser.

Any advice would be appreciated.

The processes are like below when listed by ps
