[erlang-questions] Any tcp related changes in R15B* that might cause this?

No, according to Kenneth

http://erlang.org/pipermail/erlang-questions/2011-June/059464.html

they support at least 2 versions back, so R15B should load and run code
compiled with R14B and R13B.  And none of my code is compiled with HiPE
or native so that's not an issue here.
