[plug] netscape stalling

[Evan Lau]

Hi all,

I have found the problem with stalling of internet connections. Just wanted
to let you all know out there.

Apparently the problem is that I have "rhnsd" running, which is the daemon
to automatically connect to the Red Hat servers to look for updates etc.
Also apparently, "rhnsd" leaks file descriptors and after a while it runs
out of file descriptors. When I stopped the daemon the problem went away.
Even when I restarted it the problem was not initially there (presumably the
file descriptors were released and no problem would be apparent until some
time later). However, I have found that "rhnsd" takes up bandwidth so when
the connection says 2.5K/s, sometimes only 1K/s is going to the programme
that you actually want to receive.

There is a patch on the Red Hat server but frankly, I couldn't be bothered.

Thanks all,
Evan
