[squid-users] TCP_MISS/503

hi everyone....
I have a BIG problem I can't solve with my squid.
sometimes (randomly) I have an error in retrieving the URL
in logs it appears as:
1153487449.160 2211 10.91.195.69 TCP_MISS/503 1660 GET
http://www.sing365.com/music/lyric.nsf/Disposition-lyrics-Tool/C574A6A82533DECC48256A57002CEDB3 -
NONE/- text/html
1153487449.332 1 10.91.195.69 TCP_MISS/503 1538 GET

http://www.sing365.com/music/lyric.nsf/Disposition-lyrics-Tool/C574A6A82533DECC48256A57002CEDB3 -
NONE/- text/html

from what it's depends?
where can I find the explanation of the error codes?
regards,

fabio
