What are the possible condition might occur for daemon to hog the cpu and makes the system very slow or moved to non-responsive state?

Daemons have few threads as well.

A tiny fraction of reasons include:

infinite loops in general
low memory in general
race conditions
dead locks
starvation
spawning too many threads
forking too much
super low process priority
infinite recursion
algorithms of bad algorithmic complexity
really slow operations on numbers
something is repeated too often (e.g. a variable that is better calculated outside a loop which the compiler was unable to move out)
cache-unfriendliness
using sleep-like functions
invoking slow functions
running the daemon on a slow machine
your are being DOS-attacked
your machine is running out of electricity and tries to slow down
your CPU has a bug
your CPU has a hardware defect
your CPU is running at too low voltage
