Subject: Strange Thread related errors
Date: Thu, 7 Jan 2010 11:05:15 -0500	[thread overview]
Message-ID: <944a03771001070805k27356c9dwdc535bed8efa7bb6@mail.gmail.com> (raw)

Our Rails app has started raising exceptions (caught by hoptoad
thankfully) and I can only imagine they're related to unicorn.  I only
*think* the errors are occurring on the request after we deploy, which
upgrades the Unicorn process.  I say this because the errors are
coming from many different actions, but I haven't been able to
reproduce.

After the most recent batch of errors, I upgraded from 0.95.1 to
0.95.3, but we have not deployed again.
