[rabbitmq-discuss] Rabbitmq Stomp error

[Steve Powell]

Ram,

It looks as though the mc-ping is negotiating a STOMP connection, but
RabbitMQ's-STOMP adapter doesn't seem to cope with checking the version; the
re:split() function may not exist in your version.

I'm not sure why this blows up -- but what version of Erlang are you running on?
My version prints out this in status:

{erlang_version, "Erlang R15B (erts-5.9) [source] [64-bit] [smp:8:8]
      [async-threads:30] [hipe] [kernel-poll:true]\n"}

From your output I guess you are running R12B-3, and although we (just about)
support that for the server, the STOMP adapter needs the later re:split/2 function,
which is available in R12B-5 onwards (I think).

I'm not sure what distribution of Linux you are using, but take a look at our
page http://www.rabbitmq.com/which-erlang.html which has links to the
distribution pages and advice about which Erlang version you need. (It doesn't
mention the STOMP adapter, though, I notice.)
