Did you know that 95% of CCcam instabiliy, freezes and glitches are caused by fake caid numbers or obsolote providers that are inside your peers servers?...
Don't waste your time and receiver memory putting ignore lists in front of each C: line you receive/exchange and don't waste your brain cells thinking your ISP sucks (sometimes it does) and that someone is attacking your dns or router.
With this prio/ignore list you will have the best anti-freeze system and it only takes around 6Kb-7Kb of your receiver's memory.
Go to CCcam.cfg
Find #CAID PRIO FILE : /var/etc/CCcam.prio (take # out)
