[IronPython] HostCodeHeap leakage?

[Idan Zaltzberg]

Im running using the engine from a hosting app.

We have these lines in the startup:

ScriptRuntimeSetup setup = new ScriptRuntimeSetup();
setup.DebugMode = true;

ScriptRuntime runtime = Python.CreateRuntime(setup.Options);
engine = runtime.GetEngine("py");



Is this is the same like –X:Debug?

You reckon this could be the cause?

My guess is that’s code in the JIT heap that’s building up but I’m not 100%
certain.  How is your code being executed?  Do you have the debug option (-D
or –X:Debug) enabled?  To support debug mode we need to produce
uncollectible code which could be building up.

I am trying to find a memory/"performance" leak in an Ipy application.

Using WINDBG (!eeheap -loader), we noticed the that the LoaderHeap is
getting bigger (150MB increase per day). From the !eeheap output it seems
that the increase is due to HostCodeHeap (objects?).

As I understand these objects might be created by Ipy infra, is that right?

Is there anyway I can get more info on their content, or prevent them from
growing?

Thanks
