internal error: awaitEvent: descriptor out of range
My program reports:
Server3s.exe: internal error: awaitEvent: descriptor out of range (GHC version 6.8.2 for x86_64_unknown_freebsd) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug Abort trap: 6 (core dumped)
The core dump shows:

The full sources that are causing this issue are attached. To reproduce: run "make" then in one window run "./Server3s.exe" and in another window run "./DummyClient3s.exe". I get the crash in the Server3s program after it runs for a while.
I can provide built binaries and a core dump if it is helpful. I didn't include them yet because they are large.
