Why my Emacs lost response sometimes????

[Zhou Fei]

I m new on using emacs(v21.3)

both under RH9,MS winXP, it sometime lose
response. I am not sure it is related with terms, 
I often run ansi-term, eterm,matlab-shell in emacs.

in my intuition, it seems when it reach buttom of a file,and
then it lose repose. 

when it happen under MS winXP, emacs use 99% cup time.and
kill the emacs process, then popup a dialog,say that error
with ...stdin...
any one meets  problem like this??

how can I got the reason? where is the log of emacs?

thank you
