are you executing the script file? If you’re creating a new optimized
module each time we won’t be able to collection the optimized module
code. If on the other hand you’re just compiling it as a helper method
then when it’s done running we can collect the code.<o:p></o:p></SPAN></P>

<P class=MsoNormal><SPAN
style="FONT-SIZE: 11pt; COLOR: #1f497d; FONT-FAMILY: 'Calibri','sans-serif'">In
pre-RC1 we had a leak where creating a new PythonEngine would result in a leak
of a SystemState and ClrModule which were being hung onto by an event rooted
in the app domain. So if you’re re-creating the engine each time you
might be seeing that. Also, now that I’ve mentioned events, you might
want to check your own C# code if you’re using events: It’s easy to
forget to unhook one and leak memory because the event handler stays alive
forever.<o:p></o:p></SPAN></P>

none of those turn out to be the problem an option here would be to download
the free CLR Profiler and look at the object type that is consuming the
increased memory. It’ll give you a nice graphical display w/ a block
view of what’s referencing what. <o:p></o:p></SPAN></P>

CMOpFuncionaliad is an IPython script i wrote, it contains a class definition.
Inside the scripts i use components defined in some assemblies i made (these
are already loaded into the CLR). The problem is, after the Engine takes
the usual 12M+- of memory it needs, every time the script executes it consumes
2M more, i dont have a clue why is this...Does this version of IP have memory
problems ? Or what else could be ?? If you need to see CMOpFuncionalidad.py
let me know and ill send it....<o:p></o:p></SPAN></P></DIV>
