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

[Anthony Molinaro]

Hi,

  I've been testing out R15B02 on one of our production machines
(CentOS 5, erlang compiled from source), and comparing it to the
same system running on R14B04.  The code is the same (it was all
compiled with R14B04, and deployed on both systems).

On the R15B02 I see this error crop up every so often

2012-12-01 00:01:33 =CRASH REPORT====
  crasher:
    initial call: mochiweb_acceptor:init/3

It doesn't happen extremely often (once or twice a minute), but its enough
to make me wary of an upgrade.

I looked through all the readme's for R15B, R15B01 and R15B02 but didn't
find anything which looked like it could be a cause.

Anyone have any ideas?

Thanks,

-Anthony
