What is this process doing? [127.0.1.1-manag]

cx flag

I am working with a system of four nodes with a share network file system. I was checking the processes running one of the nodes, since the system is slow and I have stumbled upon these processes:

root      798888 19.4  0.0      0     0 ?        R    11:33  38:30 [nfsd]
root      798889 19.8  0.0      0     0 ?        R    11:33  39:07 [nfsd]
root      798890 20.1  0.0      0     0 ?        R    11:33  39:51 [nfsd]

root      798894 27.8  0.0      0     0 ?        R    11:33  55:04 [nfsd]
root      798895 34.2  0.0      0     0 ?        R    11:33  67:35 [nfsd]
root      908884 99.7  0.0      0     0 ?        R    13:11  99:17 [127.0.1.1-manag]

While it's relatively clear what the nfsd processes are doing, I don't understand what [127.0.1.1-manag] is. Can you give me some detail about it?

[Edit] Here the output of pstree

Use `pstree` on that process to see what started it. Which version of Ubuntu?

Use `pstree` **on that process**, so `pstree -psa <pid>` or similar, please, not just running `pstree` without any arguments. And that is the kernel version. Which version of ***Ubuntu***?

It's Ubuntu 22.04.2 LTS

If I run pstree -psa 908884 I get a very long output, it does not fit in the terminal
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
