procstat(1) [-f], proto=stream without addresses

[Harry Schmalzbauer]

 Hello,

I'm in foreign waters and try gather debugging info.
One thing I noticed is that procstst(1) doesn't show any addresses for
my evil process.
Excerpt:

USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS
squid negotiate_ 597 1 stream -> ??
squid negotiate_ 596 0 stream -> ??
squid negotiate_ 596 1 stream -> ??
squid negotiate_ 595 0 stream -> ??
… (lots more snipped)
squid squid 586 10 stream -> ??
squid squid 586 12 stream -> ??
squid squid 586 14 stream -> ??
squid squid 586 16 stream -> ??
squid squid 586 18 stream -> ??
… (lots more snipped)

Simple question: Is this a "legal" state?
Any hints for further readings on this topic highly appreciated!

Thanks,
