      Description

      Rails app crashes after a random period of time when running on Thin on OpenSolaris. Error output by Thin is:

      Assertion failed: nbytes > 0, file ed.cpp, line 622
      Abort (core dumped)

      Which indicates that the problem occurred within native code in the eventmachine gem.

      The assertion checks that there are bytes available to be written on a call to eventmachine's Write(). At the time of the crash OutboundPages.size() = 0
      OutboundPages is the deque used to queue pages of data for writing.

      Stack trace:
