Subject: Errno::ENXIO (Device not configured) when using net/https from rails

I have the following code that creates a https connection from within
a rails controller.  Works fine except that if it doesn't get called
for a few hours it starts throwing an exception until I restart rails
(apache1.3 + scgi).  I wonder if something here isn't thread safe?
Just a guess.

@postdata = nil
headers = { 'Referer' => '', 'Content-Type' =>
'application/x-www-form-urlencoded' }
@postdata = "directauth=1&user=#{user}&pass=#{@password}"
site = Net::HTTP.new( 'mysite.com', 443 )
site.use_ssl = true
response = site.post('/login', @postdata, headers)

And this is the backtrace:

Errno::ENXIO (Device not configured):
