Ruby 1.8.7p249 + rails 2.3.5 + Snow Leopard = hung processes?

A few weeks ago I updated my development computer to Snow Leopard
(finally). I put it off because I was in the middle of a project, and
it seems its a good thing I did. Last week I started something new and
it seems that any rails related ruby process will get … stuck, I
guess is the best word. I’ve seen it happen as soon as a minute, or
take as long as an hour. It happens for script/server and script/
runner based processes; as far as I’ve been able to tell, it doesn’t
happen with pure ruby processes, but then again the test script I used
wasn’t trying to do things like connect to a MySQL DB. When the
processes get stuck, control-c does not stop them, they have to be
forced to quit with “kill -9”.

Has anyone else seen this?



Some info from my environment…

ruby --version

I found this blog article just after posting:

I figured I’d try his fix for mongrel, which involves uninstalling the
gem and re-installing it. But whenever I try to run “sudo gem install
mongrel”, the gem process seems to hang. I’ve had it running for 10
minutes now, and with verbose output turned on, this is all its said:

sudo gem install --verbose mongrel
GET | your community gem host
302 Found

I was able to access
in my browser and the file downloaded in a few seconds, so I doubt
that’s the issue.

At the same time, I was able to run “sudo gem install thin” and there
were no problems.
