Problem:
--------
On some Mac systems running Mac OS X 10.6.8, in some cases (usually when the available physical memory had been super low for a while but then has returned to normal levels), the Internet connection is advertised to be down by Safari, Apple Mail, Opera, Firefox, OmniWeb and a bunch of other GUI apps.
But when you run command line tools such as curl, nslookup, ftp, it works perfectly fine. A remote ARD connection to the Mac systems still works, iChat still works.
Wild guess:
-----------
I would tend to assume that curl, nslookup and ftp are not using NSURL* (NSURLConnection, NSURLRequest, etc.) or CFNetwork APIs while the GUI applications probably are. So I'm wondering whether there would not have been a known issue with these APIs in Snow Leopard after they had to face memory constraints.
Question:
---------
Has there been such a known issue?
Note:
-----
Usually, rebooting these Mac systems fixes the issue.
