[squid-users] unlinked squid process

Hello

when I do "ps -ef | grep squid" I see
squid 25921 25919 0 21:04 ? 00:00:00 (unlinkd)

why it is unlinked ? I couldn't find any document to explain.

also I am using squid for accelerating my web server.
I see following message in my access log files.
TCP_MISS:FIRST_UP_PARENT "-"

would you please let me know waht that message means
and if there is any thing I should concern about
TCP_MISS:FIRST_UP_PARENT "-" 0 !!!!

Thanks
