[Chilli] 100% cpu problem

[David Bird]

Wichert asked a good question; are you using SSL features of
CoovaChilli? 

For info on gdb, you can google for it, of course. Here is a quick howto
page:
http://www.freebsd.org/doc/en/books/developers-handbook/debugging.html

For strace, use "strace -p <pid>" and you will see the system calls
being executed - if it is using 100%, there must be a runaway loop
occurring.
