Strange user SS visible during sockstat -4 -l

Hello,
When I display sockstat listen command I can see a very different user SS listed on a list of active services.
Code:
# sockstat -4 -l
USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS
SS
proxy    ftp-proxy  67974 3  tcp4   127.0.0.1:8021        *:*
(... more services below ...)
I scanned the system using chkrootkit to look for a potential rootkit, but nothing has been found. What might be that? Is this a correct and valid state of running FreeBSD 12.1 server installation?

The user is listed, but it has no command and no PID. I also don't see any user like that in my /etc/passwd. After reboot process sometimes disappear and I don't always see SS on the list of running services. The kernel level security is 3.

I also checked different FreeBSD 12.1 installation on VirtualBox and I don't have SS user on sockstat -4 -l list.

What is SS? Should I care? What tools do you use to scan for rootkits beside a chkrootkit (maybe it is outdated and should not be used in 2020)?

Regards,
Marcin

Are you sure you've not narrowed your terminal to 71 columns wide? If you do that, the "SS" at the end of "ADDRESS" wraps around to the next line.
