why does nscd need to be restarted daily?

qwertyjjj · 02-03-2010, 12:00 PM

I was having a problem on my squid server whereby 1 website would timeout daily and return a nscd not found error: www.skyplayer.com
There may be other sites but this is the only one I know of. A selection of other sites still work correctly, which is the strange thing.
I have found that by restarting the dns cache everything works again:
/etc/init.d/nscd restart

Any ideas on the cause of the problem?
Problem is I never know quite when this will timeout so it is not very good for people accessing that site on the server.

Almost sounds like www.skyplayer.com is changing it's ip address everyday.
BUt I bet it's more like their cluster of servers/machines is redirecting you to a different node in their cluster everyday.

Hopefully someone will provide a more technical/informative answer than I.

But their cluster of servers is back end isn't it? The DNS should point to only 1 skyplayer site?
Just happened again today. I restart nscd and all is okay.
Out of interest, will restarting nscd throw out any existing connections? I can use a temporary bodge to restart nscd every 2 hrs but I don't want to disconnect any existing squid users.
