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
