Sorry for the delayed response; I just discovered that Gmail has been
queuing up a bunch of my e-mail messages since June 5 (still not sure

I don't know anything about your application, but it's pretty clear
from the stack trace that the error's occurring way down in Ruby's I/O
libraries, which FXRuby has nothing to do with. You say your
application has been running fine for the past six months; have you
recently upgraded the version of Ruby that you're using (say, a newer
version of the one-click installer for Ruby)? Or is it possible that
something has changed in the remote service that your application is
accessing over the network?

I'm sorry I can't be of more help, other than to say that based on the
stack trace you've shown, I don't see any evidence that FXRuby is at

Hope this helps,
