HI Achilleas,
You could just write your own class that does that, and modify the <import>s and
<make> in the .xml. BUT then you yourself are in charge of making sure you don't
concurrently access block members in damaging ways.
However, these crashes you see are suboptimal. You should maybe file a bug on
gnuradio.org, so that this doesn't get lost in time.
Greetings,
Marcus

I have an application that uses two probes/function_probe blocks
and an xmlrpc client.
Most of the times I see that the two threads are crushing, I guess making
concurrent requests to the SimpleXMLRPCServer.
I googled it and I found that the SimpleXMLRPCServer cannot by default handle these
cases, but if it is derived by the "*MixIn" classes you can handle concurrent
requests.
Is there something obvious and simple that needs to be changed in the
xmlrpc_server.xml block?
thanks
