My investigation shows even 1 random chosen ip address makes squid cpu usage about 30% . I have chosen that ip address based on users with TAG_NONE/400 errors . I've found that a kind of request makes a loop in squid . Wireshark shows infinite loop of X-Squid-Error: ERR_INVALID_REQ 0 and X-Squid-Error: ERR_INVALID_URL 0 which makes high cpu usage . Please find the attachements .
