[xep-support] Queueing in EnMasse

Hi all,

We are using EnMasse with it's SOAP interface, Fairy, to manage a
cluster of XEP instances but we are having problems with queueing
submitted jobs. We have our own front-end (we call it Eiocha) and this
does lots of pre-processing and central handling of binary files etc.
before then sending the xsl-fo onto EnMasse for processing. However,
if we try to send more SOAP requests than there are instances of XEP,
EnMasse effectively hangs. When we then kill the SOAP connections,
EnMasse then throws an exception and crashes out. EnMasse does not
seem to have very much control over logging and letting us know what
it is having problems with so we can't really tell what's going on. If
we throttle the connections it works fine (although nothing ever shows
up listed in the 'submitted' section of the web status page) but if
it's not going to do queueing we might as well not bother with EnMasse
and talk directly to the XEP instances.

Has anyone seen a similar problem? Or know how to turn on additional

If we did decide to dump EnMasse and talk to XEP directly, do we need
to pay for an additional product or is there some sort of tcp-based
comms available as part of the standard XEP package (or as part of the
EnMasse license)? We are developers so we are not going to be phased
by complex protocols (we are just lazy and would prefer it if EnMasse
did it for us!) :)

Thanks in advance,
