R devel - Aug 2010 - DetachedEval Issues

Hello everyone,
I have been attempting to make use of the newly implemented detachedEval
functionality and I am having a few teething issues.
My code works fine when tested with both the Client and the Server on a single
machine, but issues arise when I run them separately.Possibly because the local
/ local connection is running voer a Unix socket rather than tcp proper?
Rsession* theSession;theSession =
rc->detachedEval("source(\"hdlc_processing.r\")");delete
rc;
rc = new Rconnection(theSession);rc->connect();

Owing to firewall issues I am having to make use of an ssh tunnel for the
connection, hence the manual override of the port number.Thus I am in fact using
this:
Rsession* testSession = new
Rsession(theSession->host(),6311,theSession->key());rc = new
Rconnection(testSession);rc->connect();
This results in the following being outputted on the Rserve debug side.
session: resuming session, waiting for connections.connection accepted.sending
ID string.
header read result: 16DUMP [16]: 31 be 18 07 15 57 93 6f 9d a3 53 56 99 f4 3b
7fdiscarding buffer because too big (awaiting 1871927061 bytes)
Any help would be greatly appreciated.
Thank You
Martin Kerr

I presume you're talking about Rserve? Please use the proper mailing list
rosuda-stats-devel for that.

Which is entirely wrong - sessions don't re-attach to the server but to the
random port generated on detach by the client.

Cheers,
