<p class=MsoNormal>Hi there,<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; I&#8217;ve
found an issue in Mono 2.6.0 using a self hosted WCF service and was wondering
if anyone had seen this before (Mono trace below).<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal style='text-indent:36.0pt'>It appears to be caused by firing
in a request to the Service that takes a long time and while that request is
still running firing in another one.&nbsp; I&#8217;ve tried with both a
Singleton service instance with ConcurrencyMode.Single and a service host with
a type and ConcurrencyMode.Multiple but both seem to have the same problem.&nbsp;
<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal style='text-indent:36.0pt'>I&#8217;m just trying the latest svn
and will try to pinpoint the issue, but any help / pointers would be appreciated!<o:p></o:p></p>
