I just stumbled upon this great tutorial where there are listed probably all CCcam errors and possible solutions for them. For this tutorial to be useful you need change/add one line in CCcam.cfg and start CCcam with special command. Here is how you need to do it:

1. Run CCcam from telnet with this command:/var/bin/CCcam -d >>/var/log/debug &

2. If you have a linux server like Ubuntu, you can add this line into CCcam.cfg: DEBUG: yes
All debugging data is then automatically stored here and without the need to use upper command: /var/log/debug
